in support of its Arab allies, used its naval strength in the Mediterranean to act as a major restraint on the US Navy. America features prominently in Arab conspiracy theories purporting to explain the June 1967 defeat. Mohamed Hassanein Heikal, a confidant of Nasser, claims that President Lyndon B.

Others however, including the then United States Secretary of State Dean Rusk, Chief of Naval Operations at the time, Admiral Thomas Moorer, some survivors of the attack and intelligence officials familiar with transcripts of intercepted signals on the day, have rejected these conclusions as unsatisfactory and maintain that the attack was made in the knowledge that the
