Don't hold your breath for the truth on this in our life time.
Even if we buy the lie that Israel did not know it was a USA ship, how do they explain the shooting of men in the life rafts? Regardless of what side of a conflict a person is on, shooting at life rafts is not permitted under civilized rules of war. (sort of an oxymoron isn't it)
The US government is just a guilty of a cover up and lies as Israel.
There must (I hope) come a time in everyones life when they stop believing the fairy tales that any government is there to protect you. It is about power and power only. Does not matter if it is left, right, center, the citizens are simply to be ruled.
Do you have a theory on George W Bush ordering the USAF to attack Canadaian troops in Afghanistan?
