To you folks who insist that it's not possible for thousands of people in government to keep a secret: Tell me how they managed it with the Manhattan Project, for starters.
From the “Moorer Commission” (Chaired by Adm. Moorer) investigated the attack [USS Liberty] and made the following findings:
“We, the undersigned, having undertaken an independent investigation of Israel's attack on USS Liberty, including eyewitness testimony from surviving crewmembers, a review of naval and other official records, an examination of official statements by the Israeli and American governments, a study of the conclusions of all previous official inquiries, and a consideration of important new evidence and recent statements from individuals having direct knowledge of the attack or the cover up, hereby find the following:
7. That although Liberty was saved from almost certain destruction through the heroic efforts of the ship's Captain, William L. McGonagle (MOH), and his brave crew,
surviving crewmembers were later threatened with "court-martial, imprisonment or worse" if they exposed the truth; and were abandoned by their own government;
8. That due to the influence of Israel's powerful supporters in the United States, the White House deliberately covered up the facts of this attack from the American people;
9. That due to continuing pressure by the pro-Israel lobby in the United States, this attack remains the only serious naval incident that has never been thoroughly investigated by Congress;
to this day, no surviving crewmember has been permitted to officially and publicly testify about the attack;
11. That the truth about Israel's attack and subsequent White House cover-up continues to be officially concealed from the American people to the present day and is a national disgrace;
Who made up the “Moorer Commission”,
“In 2003, an independent commission of highly regarded experts was created to look into the matter. The Commission consisted of Admiral Thomas H. Moorer, United States Navy (Ret.), Former Chairman, Joint Chiefs of Staff; General Raymond G. Davis, United States Marine Corps, (MOH), Former Assistant Commandant of The Marine Corps; Rear Admiral Merlin Staring, United States Navy (Ret.), Former Judge Advocate General Of The Navy; and Ambassador James Akins (Ret.), Former United States Ambassador to Saudi Arabia.”
