The U.S. doesn't PUT them into power. They rise to power and we back they because the alternative is worse. Like FDR said about Samozo, "He's a son of a bitch but he's our son of a bitch".

most dictators are put into power with the help of western intelligence
Mohammad Reza Sha, General Pinochet, Saddam Hussein, and to many others to name.But you can research at cia.gov
These men were funded and/or paramilitary supported by CIA and MI6 clandestine operations. A U.S. puppet dictator is allowed to oppress and rob his country as long as the natural resources get exported and they leave nothing for the people or as bzignew Brzezinski calls them "vassals" of the U.S. Empire is hard work
