USS Liberty Attack Conspiracy Theory

Overview

On June 8, 1967 — the fourth day of the Six-Day War between Israel and its Arab neighbors — Israeli Air Force jets and Israeli Navy torpedo boats attacked the USS Liberty, a US Navy technical research ship (intelligence-gathering vessel), in international waters approximately 14 nautical miles off the coast of the Sinai Peninsula. Over the course of approximately 75 minutes, Israeli forces strafed the ship with cannon fire, hit it with napalm, torpedoed it, and machine-gunned sailors attempting to abandon ship in life rafts. By the time the attack ended, 34 American sailors were dead and 171 were wounded — nearly 70% of the crew became casualties.

Israel immediately claimed the attack was a tragic case of mistaken identity — that it had confused the USS Liberty with an Egyptian horse transport ship. The US government accepted this explanation, and the incident was quietly buried. No American investigation ever held Israel accountable, and survivors were ordered to remain silent under threat of court martial and imprisonment.

The USS Liberty incident is one of the most enduring military conspiracy theories in American history. The controversy is sustained not by fringe theorists but by the crew members who survived the attack, by senior American military and intelligence officials who investigated it, and by declassified documents that contradict the official narrative. Admiral Thomas Moorer, who served as Chairman of the Joint Chiefs of Staff from 1970-1974, called the attack deliberate and the subsequent investigation “one of the classic all-American cover-ups.”

The Attack

Pre-Attack Reconnaissance

Before the attack, the USS Liberty was operating in international waters, clearly marked as an American vessel:

• The ship flew a large American flag (5 by 8 feet; a holiday-sized flag was later raised during the attack, measuring 7 by 13 feet)
• “GTR-5” (the ship’s hull number) was painted on both the bow and stern in letters and numbers 10 feet high
• Israeli reconnaissance aircraft had overflown the ship at least eight times in the hours preceding the attack, with some passes at mast height (close enough for visual identification)
• The Liberty was a distinctive vessel — a converted Victory-class cargo ship bristling with antennas and surveillance equipment, bearing no resemblance to the Egyptian horse transport (El Quseir) Israel claimed to have mistaken it for
• The El Quseir was less than half the Liberty’s displacement, a different shape, and was in port in Alexandria at the time

The Air Attack

Beginning at approximately 1358 local time, unmarked Israeli Mirage III and Mystère fighters attacked the Liberty:

• Initial passes used cannon fire and rockets, targeting the ship’s communications antennas
• Subsequent passes dropped napalm on the deck
• The attack continued for approximately 20 minutes by air
• Crew members reported that the attacking aircraft had no national markings — standard practice for false flag operations but highly unusual for a “friendly fire” incident
• Multiple radio frequencies were jammed simultaneously, preventing the Liberty from calling for help — a capability requiring knowledge of which frequencies to jam

The Torpedo Boat Attack

After the air attack, three Israeli torpedo boats approached and attacked:

• The boats launched five torpedoes, one of which struck the ship, blowing a 40-foot hole in the hull and killing 25 men in a single compartment
• The torpedo boats also strafed the ship with cannon fire
• When sailors attempted to abandon ship and launched life rafts, the torpedo boats machine-gunned the life rafts — a violation of international law regardless of the target’s identity
• The torpedo boats circled the ship for an extended period

Rescue Delayed

Most controversially, the USS Liberty’s distress calls were received by the US Sixth Fleet, which launched rescue aircraft:

• Twice, rescue aircraft were recalled on orders from Washington
• Secretary of Defense Robert McNamara personally ordered the aircraft recalled
• President Lyndon B. Johnson reportedly said he didn’t care if the ship sank — “I will not embarrass our ally”
• It took 17 hours for rescue to arrive — an extraordinary delay given the fleet’s proximity
• By the time help arrived, the surviving crew had kept the ship afloat through heroic damage control efforts

Captain McGonagle’s Medal of Honor

Captain William McGonagle, who remained at the conn despite severe leg wounds and directed the ship’s survival, was awarded the Medal of Honor. In an unprecedented departure from protocol:

• The Medal of Honor ceremony was held at the Washington Navy Yard rather than the White House
• President Johnson did not present the medal personally — the only time in modern history a Medal of Honor was not presented by the President
• The citation did not mention Israel as the attacker
• Survivors interpreted this as evidence that the government was covering up Israeli responsibility

Key Claims

Deliberate Attack Theory

Survivors and their supporters argue the attack was deliberate based on:

1. Hours of reconnaissance: Israeli aircraft identified the ship over hours of overflights
2. Unmarked aircraft: Attacking planes bore no national insignia
3. Communications jamming: All five emergency radio frequencies were simultaneously jammed — requiring advance knowledge of which frequencies to target
4. Extended duration: The attack lasted 75 minutes — sufficient time for identification even if initial recognition failed
5. Life raft targeting: Machine-gunning life rafts demonstrates intent to prevent survivors, inconsistent with a “mistake”
6. Rescue recall: Washington’s recall of rescue aircraft suggests foreknowledge or complicity
7. Ship identification: The Liberty bore absolutely no resemblance to the ship Israel claimed to have mistaken it for
8. Flag visibility: Multiple survivors and Israeli pilots (in later interviews) confirmed the American flag was visible

The Intelligence Interception Theory

The most common theory about why Israel attacked:

• The Liberty was a signals intelligence (SIGINT) vessel intercepting communications in the area
• It may have intercepted Israeli communications about:
  • Plans to attack the Golan Heights (Syria) before the UN could enforce a ceasefire
  • Evidence of Israeli forces executing Egyptian prisoners of war in the Sinai
  • Communications revealing the scope of Israeli territorial ambitions
• Israel attacked to prevent this intelligence from reaching Washington and potentially constraining Israeli military operations

The False Flag Theory

A more controversial theory holds the attack was intended as a false flag:

• The ship was to be sunk with all hands lost
• The attack, by unmarked aircraft, would be blamed on Egypt
• This would draw the United States into the war on Israel’s side
• The plan failed because the Liberty refused to sink and crew members managed to transmit a distress call despite the jamming
• This theory parallels Operation Northwoods, a 1962 plan (never executed) for false flag attacks to justify war with Cuba

The Johnson Complicity Theory

Some theories go further, alleging US government foreknowledge:

• Johnson’s alleged statement about not embarrassing “our ally”
• McNamara’s personal recall of rescue aircraft
• The rushed Court of Inquiry and gag orders on survivors
• Johnson’s personal political relationships with pro-Israel supporters and donors
• Potential coordination between US and Israeli intelligence on the attack

The Investigation Cover-Up

The Navy Court of Inquiry

The US Navy’s investigation has been extensively criticized:

• Completed in just one week — an impossibly short time for an incident of this magnitude
• Survivors testified that they were instructed what to say and what to omit
• The inquiry’s legal counsel, Captain Ward Boston, later signed a sworn affidavit stating:
  • President Johnson and Secretary McNamara had ordered the investigation to conclude the attack was accidental
  • The evidence was “ichael clear” that the attack was deliberate
  • He was “ichael ordered” to reach a predetermined conclusion
• No Israeli military personnel were interviewed
• Physical evidence, including recordings of Israeli pilot communications, was classified

Survivor Silence

After the investigation:

• Crew members were individually threatened with court martial and imprisonment if they discussed the attack publicly
• Many survivors did not speak about the incident for decades
• The Liberty Veterans Association was formed years later to advocate for a proper investigation
• Survivors have consistently and unanimously maintained the attack was deliberate

The Moorer Commission

In 2003, Admiral Thomas Moorer (former Chairman of the Joint Chiefs of Staff) convened an independent commission that concluded:

• The attack was deliberate
• The Israeli excuse of mistaken identity was implausible
• The US government covered up the truth to protect the US-Israel relationship
• A formal Congressional investigation was warranted

Despite this, no Congressional investigation has ever been conducted.

Declassified NSA Documents

NSA documents declassified in various releases have revealed:

• The NSA intercepted Israeli communications during the attack
• Transcripts reportedly include Israeli pilots identifying the ship as American before attacking
• The full transcripts remain partially classified
• Released portions have been interpreted differently by the two sides of the debate

The Israeli Position

Israel’s official position:

• The attack was a tragic case of mistaken identity during the fog of war
• Israeli forces confused the Liberty with the Egyptian ship El Quseir
• Identification was hindered by the ship’s distance from shore and atmospheric conditions
• Israel apologized and paid $6.9 million in compensation to the families of the dead, $3.5 million to the wounded, and $6 million for the damaged ship
• An Israeli investigation found procedural errors but no intentional wrongdoing

Critics note: Israel’s total compensation of approximately $16 million was modest even for 1967, and the rapid payment was seen as an effort to close the matter quickly.

Key Figures

• Captain William McGonagle — Liberty’s commanding officer, Medal of Honor recipient; maintained until his death in 1999 that the attack was deliberate
• Admiral Thomas Moorer — Chairman of the Joint Chiefs (1970-74); called the cover-up “one of the most shameful acts in American history”
• Captain Ward Boston — Legal counsel for the Court of Inquiry; signed affidavit alleging ordered cover-up
• Lyndon B. Johnson — US President who allegedly ordered rescue aircraft recalled
• Robert McNamara — Secretary of Defense who personally recalled rescue flights
• Dean Rusk — Secretary of State who later said “I was never satisfied with the Israeli explanation”
• James Bamford — NSA historian who investigated the incident for Body of Secrets
• Richard Helms — CIA Director who reportedly believed the attack was deliberate

Cultural Impact

The USS Liberty incident has had lasting effects on:

• US-Israel relations discourse: The incident is frequently cited by critics of US-Israel policy as evidence that the relationship operates outside normal accountability
• Military trust: The treatment of Liberty survivors exemplifies government willingness to sacrifice military personnel for political alliances
• Cover-up precedent: The incident is cited alongside other military cover-ups (Gulf of Tonkin, Pat Tillman, Jessica Lynch) as evidence of systemic military dishonesty
• False flag awareness: The incident contributed to public awareness of false flag operations as a real phenomenon
