To dispassionately watch this documentary and call the attack on the USS Liberty "friendly fire" requires a feat of mental acrobatics of such colossal proportions that I can only see such claims as pure disingenuousness.
The sailors on the Liberty are interviewed at length, and offer a consistent yet chilling account of how Israeli fighter aircraft and torpedo boats systematically slaughter and maim American military personnel. This done with patent obvious intent since the navy vessel they are strafing is flying the flag of their closest ally and benefactor.
The reason's for this attack, appear to lie in Israel's build up to its invasion of the Golan Heights, an action that a spy ship like the Liberty would certainly have been monitoring.
At risk of simply regurgitating what is already exceedingly well documented online and in print, all I would ask of skeptics is to watch this DVD, and then go to the USS Liberty veterans own webpage.
This attack was an outrage, yet proved with savage irony the pernicious influence that Israel has effected upon our government. 34 dead and 171 wounded deserve far better than the under the rug sweeping they have received.
