When Carter arranged for the Shah to be replaced by the flakes and nuts who are still running Iran because the Shah wasn’t willing to pay Jimmah and his buddies their payoffs, he started the cold war with Iran.
Jimmah Carter was naive to believe the Iranian Revolution was only carried out by students and workers. He thought it was going to become democratic socialist/communist which was fine by him.
But the Islamic Revolution that picked up where they left off was the result. The ones most willing to be ruthless and bloodthirsty will always win.
A student who thought that democracy was winning, went back to Iran to help. He was lined up and shot by the Islamic regime.
