They have been completely amoral all along. It's about protecting their resources as they see it. They hire them and fire them. Gaddafi, The Shah, Saddam. Hamas were encouraged and funded to counter Arafat.It seems historically, the USA pick and choose who is good and who is bad. If you go back far enough, Bin Laden was trained by the CIA, and in the early 80's they tried to cosy up to Saddam.
