Your source is not academic or credible. The first paragraph on the site establishes that the site has a conspiracy agenda. Ussliberty.org starts:
On June 8, 1967, US Navy intelligence ship USS Liberty was suddenly and brutally attacked on the high seas in international waters by the air and naval forces of Israel. The Israeli forces attacked with full knowledge that this was an American ship and lied about it. Survivors have been forbidden for 40 years to tell their story under oath to the American public. The USS Liberty Memorial web site tells their story and is dedicated to the memory of the 34 brave men who died.
The Attack
After surveilling USS Liberty for more than nine hours with almost hourly aircraft overflights and radar tracking, the air and naval forces of Israel attacked our ship in international waters without warning. USS Liberty was identified as a US naval ship by Israeli reconnaissance aircraft nine hours before the attack and continuously tracked by Israeli radar and aircraft thereafter. Sailing in international waters at less than five knots, with no offensive armament, our ship was not a military threat to anyone.
The Israeli forces attacked without warning and without attempting to contact us. Thirty four Americans were killed in the attack and another 174 were wounded. The ship, a $40-million dollar state-of-the-art signals intelligence platform, was later declared unsalvageable and sold for scrap.
The Cover Up
Despite a near-universal consensus that the Israeli attack was made with full knowledge that USS Liberty was a US Navy ship, the Johnson administration began an immediate cover-up of this fact...
This is far from a neutral inquiry.
Despite the fact that none of the sound files are working with me, for our purposes I'll assume they say what you say they do. This does nothing to remedy the fact that there is no counter testimony presented.
Visual contact
During the morning of the attack, early June 8, the ship was overflown by Israeli Air Force (IAF) aircraft including a Nord Noratlas "flying boxcar" and Mirage III jet fighters eight times.[20][16] At least some of those flybys were from a close range.[21] Many Liberty crewmen gave testimony that one of the aircraft flew so close to Liberty that its propellers rattled the deck plating of the ship, and the pilots waved to the crew of Liberty, and the crewmen waved back.[22] The aircraft were hunting for Egyptian submarines, which had been spotted near the coast.[23] At about 5:45 a.m. Sinai time (GMT +2), reports were first received at Israeli Central Coastal Command (CCC) about the Liberty, identified by pilots as a destroyer and the vessel was placed on the plot board using a red marker, indicating an unknown vessel.
At 6:03 a.m. that morning, the Nord identified the ship as a U.S. supply ship, though the marker was only changed from the red 'unknown ship' to a green 'neutral ship' at 9 a.m., when CCC was ordered to do so after naval command inquired as to the marker's status. Also around 9 a.m. an Israeli pilot reported that a ship north of Arish had fired at his jet after he tried to identify the vessel, and naval command dispatched two destroyers to investigate. These destroyers returned to previous positions at 9:40 a.m. after doubts emerged during debriefing over the pilot's allegations of receiving fire. When the Nord landed and its naval observer was debriefed, the ship was further identified as the USS Liberty based on its "GTR-5" markings.[24] The ship was removed from CCC's plot board at 11 am, due to its positional information being considered stale.[25]
At 11:24 a.m., IDF General Staff Headquarters received the first of several reports that Arish on the Sinai coast was being shelled from the sea. Israeli troops in the city had seen a massive explosion and noticed two unidentified ships offshore. Though the explosion was probably the result of a burning ammunition dump, the Israelis were unaware of the fact, and both Israeli and Egyptian sources had reported shelling of the area by Egyptian warships the previous day. Investigative journalist James Bamford points out that Liberty had only four .50 caliber machine guns mounted on her decks and, thus, could not have shelled the coast.[26]
Chief of Staff Yitzhak Rabin was concerned that the supposed Egyptian shelling was the prelude to an amphibious landing that could outflank Israeli forces. Rabin reiterated the standing order to sink any unidentified ships in the area, but advised caution, as Soviet vessels were reportedly operating nearby. No fighter jets were available, and the navy was asked to intercede, with the assumption that air cover would be provided later. Naval headquarters did not react to the request in any way, and more than half an hour later, the General Staff issued a rebuke: "The coast is being shelled and you have done nothing". At 20:05 p.m., naval command dispatched three torpedo boats to find and destroy the enemy warship thought to be shelling Arish.[23] The torpedo boats were T-203, T-204 and T-206, and were from the 914th Squadron, codenamed "Pagoda".

Though Egyptian warships were known to disguise their identities with Western markings, they usually displayed Arabic letters and numbers only. Rabin ordered the torpedo boats to remain at a safe distance from the ship, and sent in two Hornet helicopters to search for survivors. These radio communications were recorded by Israel. The order also was recorded in the torpedo boat's log, although Commodore Oren alleged not to have received it. The order to cease fire was given at 2:20 p.m., 24 minutes before the torpedo boats arrived at the Liberty's position.[38]
During the interval, crewmen aboard the Liberty hoisted a large American flag to be clearly identified, but the flag was obscured by the smoke. The ship's request for assistance reached the Sixth Fleet at this time, and the aircraft carrier USS America dispatched eight aircraft. The carrier had been in the middle of strategic exercises, and the aircraft were still armed with nuclear bombs when they took off. Vice-Admiral William I. Martin recalled the aircraft minutes later. Martin feared that the Liberty's attackers were Soviet, and did not want to risk starting a nuclear war.[23]

The disgusting thing here is that your focus on the incident isn't out of remorse for the American lives lost. Quite the opposite you're highly critical of the American military, but you bring this up like propaganda as you see it as an opportunity to turn opinion against Israel by telling half truths and lying outright.
The USS Liberty incident was tragic, but there was no motive for Israel to have purposefully attacked an American vessel. Things sometimes happen in the fog of war which are unintended, and the United States itself is no stranger to this.If you weren't a self avowed Western hating socialist I'd say you should be ashamed of yourself for exploiting the deaths American servicemen to further your agenda, but considering what you are I'd say you're doing a half decent job of employing soviet era propaganda techniques.
It's actually kind of entertaining to watch and without a voice to combat it you might actually be able to sway some rather stupid people who are drawn in by your seeming authority. Presented with a rational counter argument however, aka reality, all of your false pretenses crumble.
