This is the same argument people like you said in the late 70’s when we had to get rid of the Shah of Iran. What replaced him were fun-loving muslim clerics who have done all they can to make friendly w/the U.S.
Cuba in the 1890s was suffering under Spanish misrule. We got rid of the Spanish--now they have Castro.
Wilson didn't think the Kaiser was a nice guy. After a few years of a weak democracy, Germany wound up with Hitler.
JFK got fed up with Diem. After Diem, some regimes that were no better, then a Communist dictatorship.
Jimmy Carter thought the Shah was mean...so now they have had 32 years of Islamic theocracy.
Muzorewa wasn't radical enough for Carter, so he was pushed aside in favor of Mugabe...more authentic because he was an outright Marxist.
