Most evil dictator the USA was ever chums with? (Nominations Phase)

[Commie Pinko Dirtbag]

Off the top of my head:

Pinochet, from Chile
Videla, from Argentina
Marcos, from the Phillipines
Suharto, from Indonesia
Reza Pahlavi, from Iran
Franco, from Spain
The House of Saud, from Saudi Arabia
The Duvaliers, from Haiti
Anastasio Somoza, from Nicaragua

Fell free to add any I forget. I'm not counting Saddam or Pol Pot because they ended up as "bad guys". I'm thinking dictators that were in cahoots with the US government for their entire stint at power.

And yes, Brazil had military dictators too, and they killed innocent people, but compared to the one above they were high school bullies.
