As for the Liberty, blue on blue attacks are nothing new in warfare, and the identification technology in 1967 was nowhere NEAR what it is today. The US claimed it had no ships in the area until after the attack, and expecting Israel to ignore a ship conducting surveillance on them when they were at war is no more realistic than expecting the US to look the other way if they found an unidentified ship sailing off of Oahu on Dec. 8, 1941.
Oh really?
The Attack
After surveilling USS Liberty for more than nine hours with almost hourly aircraft over flights 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 nine hours before the attack by Israeli reconnaissance aircraft 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. http://www.gtr5.com/
" . . . an act of military recklessness reflecting wanton disregard for human life."
Then Secretary of State Dean Rusk in a 10 June 1967 diplomatic note to the Israeli Ambassador.
"But I was never satisfied with the Israeli explanation. Their sustained attack to disable and sink Liberty precluded an assault by accident or soem trigger-happy local commander. Through diplomatic channels we refused to accept their explanations. I didn't believe them then, and I don't believe them to this day. The attack was outrageous."
