Others claim that the attack was deliberate and premeditated. They note that the Liberty was more than twice as large as the El Quseir, and was clearly designated with Latin rather than Arabic letters and numbers. Proponents include surviving Liberty crewmen and some former U.S. government officials, including then-CIA director Richard Helms and then-Secretary of State Dean Rusk as well as Admiral Thomas Hinman Moorer, former Chief of Naval Operations and Chairman of the Joint Chiefs of Staff.

June 6, Admiral Martin replied: “Liberty is a clearly marked United States ship in international waters, not a participant in the conflict and not a reasonable subject for attack by any nation. Request denied.” He promised, however, that in the unlikely event of an inadvertent attack, jet fighters from the Sixth Fleet could be overhead in ten minutes.
