At 10:55 on the morning of 8 June 1967, an Israeli naval officer reported a ship off Sinai as the US Navy's Liberty, hull number GTR-5, and she was marked neutral on the plot. Five minutes later the marker was erased. ^[27] About two that afternoon, Israeli jets began the USS Liberty attack, and torpedo boats followed. ^[1]

Thirty-four Americans died and 171 were wounded, by the Navy's own count. ^[25] The ship was in international waters off Egypt's Sinai coast, on the fourth day of the Six-Day War. Israel apologised within hours and called it a mistake. ^{[6] [24]}

The attack has been investigated many times. The Navy's court of inquiry found no sign the ship was targeted as an American vessel. Clark Clifford, who chaired the president's intelligence advisory board, found no evidence that Israel's high command planned it, but called it "gross negligence". ^{[23] [31]}

The CIA first said the attackers failed to identify the ship, then concluded the attack was "by mistake". ^{[16] [19]} Survivors and several former senior officials say the attackers knew exactly what they were hitting. ^{[29] [34]}

The record cannot settle that argument. In 1967 the CIA said none of the attackers' radio traffic was available to it. The National Security Agency's June report found no intercept of the attack itself. ^{[16] [20]}

Later claims of such recordings are unproven. ^{[30] [33]} The files do show what Israeli headquarters knew that morning, what could be seen from the air, and what Washington did afterwards. No document I read establishes a motive, and none is assumed here.

• Verified: Israeli aircraft and boats attacked the ship; it was in international waters; Washington's order to move away never reached it in time; US jets launched and were recalled the same day without reaching the ship; the Navy court heard no Israeli witnesses. ^{[3] [11] [21] [22] [25]}

• Contested: whether the attackers or their commanders knew the ship was American; whether the flag and hull markings were visible; why the jets were recalled when they were; whether the Navy court was pushed toward its conclusion; whether lifeboats were fired on deliberately. ^{[1] [23] [27] [29] [30]}

• Unresolved: what the Israeli pilots and boat captains said to each other during the attack; what other US and Israeli records remain classified; and why the attack happened, if it was not an error. ^{[20] [37]}

The Liberty was a converted merchant ship, 455 feet long and bristling with antennas. ^[17] The Navy called her a technical research ship. In fact she collected signals intelligence for the National Security Agency. ^{[1] [16]} Her crew of 294 included Arabic and Russian linguists, but no Hebrew speakers. ^{[1] [29]}

She carried four .50-calibre machine guns, meant to drive off boarders. ^[1] Her hull number, GTR-5, was painted in white on the bow and the stern. ^{[1] [23]} The Navy's own historian notes that the ship's real job was secret then. The Pentagon's first press release about the attack was deliberately false, and that damaged US credibility. ^[1]

When war loomed, the ship was sent to the eastern Mediterranean. She reached her patrol area, 13 to 17 miles off the north Sinai coast, on 7 June. ^[1] On 8 June she was moving slowly west, at about five knots by the Navy court's reckoning. ^[23]

For how this kind of listening ship fits into the wider history of electronic spying, see The SIGINT Revolution.

Washington had tried to pull her back before the USS Liberty attack. On the evening of 7 June, US time, the Joint Chiefs of Staff told Navy headquarters in London by phone to keep the Liberty at least 100 nautical miles from the coasts of Israel, Egypt and Syria. ^[11] Written orders followed. ^[7] None reached the ship before the attack. ^{[1] [7]}

The Navy's historian counts five messages that were misrouted or dropped. ^[1] A Joint Chiefs fact-finding team blamed human error, heavy message traffic and a failure to grasp the urgency. ^[22] The orders in force on the ship let her come within 12.5 miles of Egypt's coast and 6.5 miles of Israel's. ^[16] She was about 14 miles out at midday and about 25 miles from land when attacked. ^{[1] [11]}

A White House staff memo written that day said the Pentagon's reconnaissance office had filed the ship's track change on time. Whether her distance from shore was unwise, it said, was "for others to judge". ^[9]

Israel said it had not been told a US ship was there. Its ambassador asked Washington on 12 June for timely warning of US vessels near its shores. ^[24] Clifford noted that Israel had made no inquiry about American ships either. ^[23] The US ambassador to the United Nations had said publicly on 6 June that no US ships were within 100 miles of the fighting, the Navy historian records. ^[1]

Times below are local, which means GMT plus two hours, unless marked GMT. US and Israeli records differ by up to about ten minutes, and the CIA's "local" times run an hour ahead of Israeli time. ^{[16] [23]}

Around 2 p.m. two Israeli Mirage jets made the first pass. They fired 30-millimetre cannon at the forward superstructure. ^[1] Two Super Mystère jets followed, dropping napalm and strafing. ^[1]

The ship reported six strafing runs. ^{[11] [17]} The air attack ended about 2:10 p.m. Nine Americans had been killed or fatally wounded. ^[1]

The flag was shot away, or its halyards burned. ^[1] The ship's signal lamps and much of her communications were wrecked. ^{[1] [23]} The CIA wrote that the first word reached US commanders only after the torpedo hit. ^[16]

About 20 minutes after the jets, three Israeli motor torpedo boats closed in. ^[17] They fired machine guns and torpedoes. One torpedo struck the starboard side at the intelligence spaces and killed 25 more men: 22 sailors, two Marines and one NSA civilian. ^[1]

The hole was about 39 feet wide at the base. ^[16] The ship took a list of nine to ten degrees. ^[1]

The attack ended, the Navy historian writes, as Israeli headquarters came to doubt what had been hit. The CIA wrote that it was called off because the ship seemed to be sinking, not because she had been identified. ^{[1] [16]} Helicopters arrived and offered help. The Americans declined. ^{[8] [16]}

In Washington, a flash report reached the White House by 9:50 a.m. Washington time: an American intelligence ship had been torpedoed, and nobody knew by whom. ^[2]

The Liberty limped north-west at eight knots. Two US destroyers reached her early on 9 June. ^[11] She reached Malta on 14 June. ^[16]

Some accounts add rockets, more than 30 sorties and 12 or more aircraft. ^[29] The Navy historian calls rockets "very unlikely" from the first jets, which carried cannon, and says three of four napalm canisters missed. ^[1] Casualty counts differ by source: 171 wounded in the Navy's count, 172 to 174 elsewhere. ^{[25] [29] [34]} The Navy put the repair cost above five million dollars. ^[25]

What Israeli headquarters knew that morning

Israeli and American records agree on the basics. An Israeli reconnaissance aircraft found the ship at about six in the morning. ^{[1] [27]} By 10:55 an Israeli naval liaison officer had reported her as the US Navy ship Liberty, hull number GTR-5, and she had been marked neutral on the plot. ^[27] About five minutes later the marker was erased, because no current position was known. ^[27]

The CIA called this "the first indication" that Israel knew a US ship was nearby. ^[19] Clifford wrote that one element of the Israeli air force knew her identity by about nine o'clock and did not attack. ^[23] The CIA concluded in June that the Israelis had identified the Liberty earlier, but "were apparently not aware that they were attacking" her. ^[19]

Israel's judge went further than Israel's first summary. He found it "reasonable" to assume the head of the naval department knew an American supply ship was in the area. ^[27] He also recorded that a later pilot report of a hull marking like the Liberty's was repeated aloud on the naval command bridge, in front of the head of the naval department and the chief of naval operations. "No one present", he wrote, "had connected this report with the target attacked." ^[27]

So the argument is not about the morning. It is about whether that knowledge reached the men who attacked, and whether they could see the ship for themselves.

The earlier overflights

Clifford listed three earlier flights by unidentified aircraft, about five hours, three hours and two and a half hours before the attack. The crew could not fully identify them. He judged they were probably Israeli. ^[23]

The Navy historian disagrees. He says other Israeli flights that morning never reported on the ship, and that they are wrongly counted as surveillance. ^[1]

Israel's judge records another sighting. At about nine o'clock an Israeli pilot reported a warship 20 miles north of El Arish that, he said, had fired on him. At his debrief at 9:40 the report of fire was judged unfounded. He described a grey ship, "very bulky", with its bridge amidships. ^[27]

Early US claims were also corrected. Secretary of State Dean Rusk's first diplomatic note said two Israeli aircraft circled the ship three times, an hour before the attack. ^[12] A corrected note on 11 July replaced it, after officials fixed wrong times and statements. The new text says only that aircraft "believed to be Israeli" circled the ship several times from about 5:15 a.m. ^[13]

Reports of shelling, and a ship that seemed too fast

Israeli commanders said they had reports that El Arish was being shelled from the sea. Clifford wrote that those reports were later found to be wrong. ^[23] The Israeli judge accepted that two separate reports of shelling reached naval headquarters. ^[27] The Israeli torpedo boats then tracked a radar target at 28 to 30 knots. ^{[19] [27]}

An Israeli standing order allowed ships above 20 knots to be attacked without further identification. ^[23] Israel's own check of a ship manual gave the Liberty's top speed as 18 knots, and on the day she was making five. ^[23] The CIA called the 30-knot figure "most bizarre", and the standing order "questionable military policy". ^[19]

What the intercepts show after the attack

The best contemporary evidence is Israeli radio traffic intercepted by the US. ^[20] At about 2:31 p.m. Israeli air control told two helicopters: "there was a warship there which we attacked." ^[20] Minutes later it said the ship had been identified as Egyptian. ^[20]

At about 3:10 p.m. a helicopter told a torpedo boat that "G.T.R.-5" was written on the ship and asked if that meant anything. The boat said no. ^[20]

Two minutes later the helicopter reported an American flag. Control asked it to check "if this is really an American flag". ^[20]

On 13 June the CIA said the traffic left "little doubt" the Israelis had failed to identify the ship before or during the attack. ^[16] White House adviser Walt Rostow told President Johnson the tapes showed "some honest ambiguity about the ship after the attack", and possibly a breakdown on the Israeli side. ^[14] The State Department's intelligence bureau saw something else: a 58-minute delay before anyone established the ship's identity, and "an extraordinary lack of concern" about whether the target was hostile. ^[17]

That describes recklessness. It does not prove intent.

One secondhand report points the other way. An official at Israel Aircraft Industries told an American source he had heard an Israeli aircraft report a ship with a US flag. The pilot was told to look again and confirmed the flag two or three times. ^[17]

The US attaché's source thought this probably happened before 8:00 in the morning. ^[15] Nobody could say whether it described the attack, but Clifford counted it among his grounds for thinking the earlier overflights were Israeli. ^{[17] [23]}

The weather was clear and the sea calm. ^[23] The ship's normal five-by-eight-foot flag flew at the masthead until the air attack shot it down. A larger flag, about 13 feet long, went up before the torpedo boats arrived. ^[23] The Navy historian adds that smoke hid it from the boats, and that Israeli gun-camera film shows no flag on any pass. ^[1]

Israel's judge heard the same facts differently. The pilots, he wrote, looked for a flag and found none. The ship was grey and had guns in the bow.

A helicopter spotted a small American flag only after the attack. ^[27] A pilot read the hull number late in the air attack, and Israeli staff then ordered the boats to hold fire until the ship was identified by eye. ^{[1] [27]}

The torpedo boat commanders took the ship for the Egyptian transport El Quseir. ^{[19] [27]} American reviewers disagreed. Clifford called the mix-up "unbelievable". ^[23]

Sources disagree on how much smaller El Quseir was: a quarter of the displacement and 180 feet shorter in Clifford's account, less than two-thirds the size in the Navy historian's, less than half in the US attaché's. ^{[1] [10] [23]} The CIA said an overzealous pilot could mistake one for the other. ^[16] The Israeli judge studied photographs and found a likeness, especially through smoke. ^[27]

Israel also said a boat flashed "AA", meaning "identify yourself", and the Liberty flashed back the same. ^{[23] [27]} Clifford called that "demonstrably false", because the ship's signal lamps had been destroyed. ^[23] The Navy historian says accounts conflict about a hand lamp. ^[1]

The CIA's own timeline logs the Liberty firing at a torpedo boat at 2,000 yards just before the hit. The Navy historian says one .50-calibre round was fired. ^{[1] [16]}

The Liberty's report reached the Sixth Fleet at about 1252 GMT, 24 minutes after the torpedo hit at about 1228. ^{[4] [17]} At 1320 GMT the fleet commander reported that he had ordered the carriers America and Saratoga to launch armed jets, and he declared the attackers hostile. ^[4] A message at 1339 GMT allowed force "including destruction", but not pursuit toward land. ^[3] The Joint Chiefs backed that at 1416 GMT. ^[3]

The fleet estimated a launch at 1345 GMT, with the first jets about an hour and a half away. ^[4] The survivors' commission says carrier help was only 40 minutes away. ^[29] On the fleet's own estimate, no jet could have arrived before the shooting stopped.

Two Pentagon records give a reason for the recall. The National Military Command Center's log says the aircraft "were recalled following" the Sixth Fleet's receipt of Israel's acknowledgment of the attack. ^[11] The CIA's chronology puts the same sequence in order. ^[16]

The timing is tight. The Sixth Fleet ordered "Recall all strikes" at 1440 GMT. ^[3] The US attaché's cable reporting Israel's apology was sent from Tel Aviv at 1414 GMT and logged at the Pentagon about 1445 GMT. ^[6] The files do not show how the fleet learned of the apology before 1440.

At 1529 GMT the Joint Chiefs cancelled the authority to use force, and all aircraft were accounted for by 1645 GMT. ^[3] Washington was also talking to Moscow. At 10:15 Washington time the State Department told the Soviet chargé that the jets were going only to investigate. At 11:00 it told him Israel had attacked the ship. ^[5]

Two US destroyers reached the Liberty early on 9 June, more than 16 hours after the attack. ^[11]

The recall remains disputed. A private commission said the White House recalled the jets while the ship was under fire. ^[29] It relied on a 1992 account by the ship's chief intelligence officer of what Admiral Lawrence Geis told him: that Defense Secretary Robert McNamara ordered a recall twice. ^[30]

A Navy technician told the commission he overheard part of the call. ^[30] These are secondhand accounts, decades old, given after Geis had died. ^[30] The Pentagon's contemporary messages show one recall order and no second launch. ^{[3] [11]}

Israel's army chief ordered a one-man inquiry four days after the attack. Colonel Ram Ron filed his report on 16 June, and the military advocate general recommended a preliminary hearing. ^[28] On 17 June Israel gave Washington a summary. It said the attack was "not in malice", involved no criminal negligence and came from "a chain of three mistakes". ^[18]

Israel's chief military prosecutor then brought seven counts of negligence. Judge Yeshayahu Yerushalmi heard 34 witnesses and read 14 exhibits. ^[27] In an interim ruling on 5 July he found that negligence "may have been committed" by the acting chief of naval operations, for not reporting the morning sighting. ^[27]

On 21 July he ruled there was not enough evidence to put anyone on trial. He said the El Quseir identification was "well within reason". He said the Liberty's failure to identify herself had contributed, and that wartime conduct is judged by a standard that "may possibly differ" from peacetime. ^[27] The lessons about cooperation between Israel's air force and navy, he added, lay outside his task. ^[27]

Israel apologised that afternoon. ^[6] The next day Prime Minister Levi Eshkol sent condolences to President Johnson and offered compensation. ^[40] The Navy historian says Israel later paid millions to the families, and that a compromise on the ship's damage was reached after a dispute. ^[1]

Limits: this was Israel's own military reviewing its own forces. The US received a summary in 1967. ^[18]

I read the judge's written decision, not the testimony or the Ram Ron report. The Israeli State Archives hold more, and I did not read it.

The Navy court of inquiry was convened on 10 June under Rear Admiral Isaac Kidd and took evidence from 11 to 17 June. It heard 19 witnesses and issued 52 findings. ^{[21] [26]} Its public summary said the court did not rule on the attackers' blame, and that "no evidence was heard from the attacking nation". ^[21] The report said there was no indication the attack was aimed at a US ship. ^[31]

A White House note of 26 June records a second layer. Rostow wrote that "Cy", the deputy defense secretary Cyrus Vance, said the court's members believed an Israeli communications failure, not planning, caused the attack. Vance advised against saying so publicly, "on the evidence we have". ^[21]

The Navy's judge advocate general wrote that Israel had admitted "a tragic accident". The Atlantic Fleet commander said inadequate Israeli identification was the reason for the attack. No one was named a party to the inquiry, and no discipline was recommended. ^[25]

Other 1967 reviews cut in different directions:

• The CIA's 13 June memo said the intercepts left "little doubt" the Israelis failed to identify the ship. ^[16] Its 21 June memo said that earlier timing statement "is in error". It concluded the attack "was by mistake", yet "indicative of gross negligence". ^[19]

• A Defense Intelligence Agency memo of 13 June said no information "conclusively" showed a premeditated attack on a ship known to be American. It called Israeli command and control "defective". ^[19]

• The State Department's intelligence bureau called it "remarkable" that no pilot identified an American ship in six strafing runs. ^[17]

• The Joint Chiefs team looked only at US communications. ^[22]

Clifford's 18 July memo is the most detailed. He found that "the weight of the evidence" was that the attacking force "originally believed their target was Egyptian". ^[23] He found nothing showing the high command made a premeditated attack on a ship known to be American. ^[23]

He added that nothing showed the top Israeli leaders knew either, and that disproving it would need access "which in all likelihood can never be achieved". ^[23] He called the mix-up with El Quseir unbelievable and the attack a "flagrant act of gross negligence", for which Israel should be held responsible and the personnel punished. ^[23]

Survivors describe clear weather, a visible flag and an attack that Captain Ward Boston said was meant to leave no survivors. ^{[29] [34]} They say Israeli boats machine-gunned life rafts. The Navy historian confirms the rafts were shredded by fire. He does not say it was deliberate. ^[1]

Boston, the court's senior legal counsel, signed an affidavit in October 2003. He said Admiral Kidd and he believed with certainty the attack was deliberate, and that Johnson and McNamara ordered Kidd to find a mistake. ^[29] He had said something similar in 2002. ^[31]

Limits: it came 36 years later. Kidd had died in 1999. Boston was counsel, not a member of the court, and his claim about orders describes what Kidd told him. ^[31] The 1967 White House note above reports a different private view of the court's members, also secondhand. ^[21]

In 2003 a commission led by Admiral Thomas Moorer, a former Joint Chiefs chairman, found "compelling evidence" of a deliberate attack. It also found the White House recalled rescue jets and covered up the facts. It asked for a new Navy court of inquiry. ^[29]

The commission was not a government body. Its evidence was survivor testimony, official records, statements by former officials and Boston's affidavit. I found no Israeli testimony in its text. ^{[29] [30]}

It cited recordings from a Navy EC-121 aircraft, gathered by the author James Bamford. ^[30] I found no such recording in the files I read.

Senior voices add weight, but they are opinions on plausibility. Moorer and former NSA director Bobby Ray Inman, as quoted in the House resolution, doubted the mistake story. ^[34] Rusk's quoted line, that Israeli aircraft identified the ship an hour before the attack, comes from his first note. ^{[12] [34]}

State replaced that note on 11 July. ^[13] The corrected note still says the ship "was or should have been identified". ^[13]

Its best advocate is A. Jay Cristol, a retired Navy captain who was a Florida federal bankruptcy judge when he wrote it. He wrote The Liberty Incident and argues that Israel took the ship for an enemy. ^[32] He cites the removal of the dawn sighting from the plot, the small or hidden flags, and the lack of any flag mention in the radio traffic for half an hour. ^[32]

The Navy's historian called Cristol's 2013 book the most thoroughly researched account he had read. He also said most books and films on the Liberty contain major inaccuracies and many have an agenda. ^[1] Cristol argues a position and the Navy historian offers an opinion. Neither is neutral evidence.

Points for a mistake: Israeli controllers' own traffic shows them guessing between Egyptian, Soviet and American. ^[20] Clifford and the CIA both found the attackers took the target for an enemy. ^{[19] [23]} Five torpedoes were fired and only one hit the intelligence compartment, which the Navy historian says weakens the claim of careful targeting. ^[1]

Points against: the weather was clear, and Israeli headquarters had identified the ship that morning. ^{[23] [27]} The jets made six strafing runs, and the boats attacked about 20 minutes later. ^{[11] [17]} Clifford found the El Quseir mix-up unbelievable, and the State Department's intelligence bureau found an "extraordinary lack of concern". ^{[17] [23]}

The number of inquiries proves less than it seems. The Moorer commission says the later reviews rested on the 1967 court's conclusion. ^[29] Cristol counts ten American and three Israeli reviews. ^[32] Repeated findings from one source count as one chain, not as thirteen.

Two other files on this site cover other Cold War records: the 1962 Operation Northwoods planning document and the 1964 Gulf of Tonkin incident. They are separate cases and are not evidence about the Liberty.

On 30 June 2026 Representative Thomas Massie, a Kentucky Republican, introduced House Resolution 1406. ^{[34] [35]} It is non-binding. It honours the 34 dead and urges the president to declassify all Liberty records held by the Defense Department, the CIA, the NSA and any other agency. ^[34]

It went to three committees. A tracker showed it still in committee, with no co-sponsors, on 18 October 2026. ^[36] The resolution's preamble is advocacy.

It cites 174 wounded, where the Navy counted 171. ^{[25] [34]} It repeats the claims about machine-gunned lifeboats, Boston and Moorer. ^[34]

Massie told the House on 8 June 2026 that the attack was no accident. Al Jazeera reported no response from the US or Israeli governments. ^[38]

On 24 August 2026 the Ninth Circuit Court of Appeals decided Kinnucan v. NSA. ^[37] Michelle Kinnucan had sought a two-volume House Appropriations Committee report on the communications failures behind the USS Liberty attack. The NSA had a copy from 1968. ^[37]

The court held the report is a congressional record outside the Freedom of Information Act. It noted the report's banner: "NOT FOR RELEASE UNLESS AND UNTIL AUTHORIZED BY COMMITTEE". ^[37] The report is therefore still unreleased.

Its subject is the US communications failure, not the attackers' knowledge. Its release would show what Washington knew about those failures. ^[37]

The National Security Agency hosts a public collection of declassified Liberty documents, listed across 17 pages. ^[39] In 2007 it released its largest batch. The NSA said the release was not meant to prove or disprove any set of conclusions. ^[33] No public index I found says how much remains classified.

The facts come from US government records, Israeli inquiry texts, court and legislative documents and named witnesses. Searches ran on 3 and 4 November 2026 with terms such as "USS Liberty attack", "USS Liberty investigation", "H.Res. 1406" and "Kinnucan Ninth Circuit". The evidence cutoff is 4 November 2026.

I read the State Department's published Liberty documents (Foreign Relations of the United States, 1964 to 1968, volume XIX), the Navy's history page, the Navy court's cover letters and endorsements, Israel's Yerushalmi decision, the Ninth Circuit opinion and the text of H.Res. 1406. I separated what officials said, what they could show and what survivors recall. Repeated reports from one source count once.

Gaps matter. The Navy court's full findings and testimony are scanned images, and I read only its endorsements; the findings are quoted from the 2003 account of them. I did not read the Ram Ron report, Israel's State Archives, the NSA's 1981 history or the books by Cristol, Bamford, James Ennes and Oren.

The NSA site blocked automated access, so I read an Internet Archive copy of one list page and the NSA report printed by the State Department. Congress.gov was blocked too, so H.Res. 1406's status rests on the Government Publishing Office record and a tracker, and later action should be checked there. I conducted no interviews.

Verified: the USS Liberty attack happened as described. Israeli aircraft and boats hit the ship in international waters. Thirty-four Americans died and 171 were wounded. Washington's order to move away did not reach the ship, and the US jets were recalled before they could arrive. ^{[1] [11] [25]}

Contested: whether the attackers knew. The Israeli account is that they did not. The Navy court, the CIA, the DIA and Clifford each stopped short of finding a deliberate attack, and Clifford found the attackers "originally believed their target was Egyptian". ^{[19] [23] [31]}

The same files record clear weather, an Israeli identification that morning, a command failure Clifford called gross negligence, and an Israeli judge who found that nobody connected a hull-marking report to the target. ^{[23] [27]}

Unresolved: what the attackers said during the attack, and why it happened if it was not an error. Motive theories exist. Moorer's letter, quoted in the House resolution, points to Israel's coming move on the Golan Heights.

The Navy historian answers that Israel had told the US of that plan about eight hours earlier. ^{[1] [34]} No document I found establishes a motive, and a motive would not prove knowledge. ^{[1] [34]}

The strongest defensible answer is narrow. The records show that a ship Israel had identified as American that morning was attacked that afternoon, and that Israel says it was taken for an enemy. The post-attack traffic is consistent with that account. ^{[20] [27]}

They do not prove the attackers knew they were firing on an American ship. They do not disprove it. Clifford wrote in 1967 that disproving high-level knowledge would need access that could "in all likelihood" never be achieved, and the public record has not changed that. ^[23]

What would change the answer: a recording or transcript of the attackers, Israeli operational orders and logs from the day, or unreleased US intelligence files. The sealed House report would add to what Washington knew about its own communications failure, not to what the attackers knew.
