The Post and Al Jazeera tape are but a small part of the volumes of evidence that Israel knew what it was doing that has yet to be released. Steve Forslundan, who was an intelligence analyst for the 544th Air Reconnaissance Technical Wing at Offutt Air Force Base in Omaha, states that the real-time intelligence he was reading as the day progressed:
"made specific reference to the efforts to direct the jets to the target which was identified as American numerous times by the ground controller. Upon arrival, the aircraft specifically identified the target and mentioned the American flag she was flying. There were frequent operational transmissions from the pilots to the ground base describing the strafing runs. The ground control began asking about the status of the target and whether it was sinking. They stressed that the target must be sunk and leave no trace."
Prior to the airing of the documentary "The Day Israel Attacked America," a long list of public figures, including those of highest US military rank, have backed the survivors' contention that the Israelis meant to sink the Liberty knowing full well that the ship was American. These include Secretary of State Dean Rusk, who held that office at the time of the incident, Director of the NSA Admiral Bobby Ray Inman, US Senator Adlai Stevenson, and Chairman of the Joint Chiefs of Staff Admiral Thomas Moorer. Moorer concluded in his own investigation:
"In attacking the USS Liberty, Israel committed acts of murder against U.S. servicemen and an act of war against the United States."
