The Shah removed himself. He was an incompetent dictator, they always have a short shelf life.
And really, so was Hussein.
Really if you think bad people being ousted is bad, you’re the idiot.
I will ignore your unnecessary personal insult, and instead agree with you to a point. Yes, the Shah was incompetent. And yes, Saddam was evil.
So is it a good idea for the United States to interfere in another country, and oust a bad leader? Maybe. But we’d better have a darn good idea about what’s coming next, who the replacement will be.
In both cases it seems to me that we traded down. The region would be better off had Saddam and the Shah been left power. Of course your mileage may vary.
