Don't try to go up against me in a history contest, please. The Carter administration thought backing Khomeini would've been a good idea, turned around and bit him in the backside when the sacking of the US Embassy happened and it was used as a major campaigning card by Carter's rivals later on. It's called being cunning. The secret Wolfowitz memos to Israel during the Iran Contra Affair already showed how the situation in Iran had gone out of hand and how Iran wasn't going to be an Israel ally as the Begin regime had thought in the early phases of the Revolution.
The most ignorant nation belongs to Pakistan, who acts like it's been through so much and yet has never taken a proud, brave stance in history. People like you are disgusting. Hang yourself and be done with it. Pakistan has never, ever, done anything good vis-a-vis anything unrelated to India. Drop the Holier-than-thou attitude.
