The cover-up of the unprovoked attack by Israel upon the U.S.S. Liberty in international waters on a bright, sunny day, when the Liberty was flying an enormous American flag, is ongoing. Because Israel.
Here's a link to the website kept by the U.S.S. Liberty survivors: http://www.gtr5.com/
From the website:
"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.
"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."
Why did Israel do this? According to former CIA analyst Ray McGovern:
"One view is that the Israelis did not want the United States to find out they were massing troops to seize the Golan Heights from Syria and wanted to deprive the United States of the opportunity to argue against such a move.
"James Bamford, in Body of Secrets, adduces evidence, including reporting from an Israeli journalist eyewitness and an Israeli military historian, of wholesale killing of Egyptian prisoners of war at the coastal town of El Arish in the Sinai.
"The Liberty was patrolling directly opposite El Arish in international waters but within easy range to pick up intelligence on what was going on there. And the Israelis were well aware." http://www.alternet.org/story/64833/the_%22hidden_day%22_israel_deliberately_attacked_american_ship,_killing_34
