Need help on sources for Che Guevara.

[Sholan]

Well, I need some resources/websites to cite on the things U.S. government has supported to keep South American countries. (United Fruit company etc. stuff like that)

And I need somewhere to quote Che when he says something about justifying force in a revolution if it is not possible through a peaceful way or something like that. I think it was from his guerilla warfare book. (I know, what the heck am I doing a paper on him without that book right?)

I have the "Che: Revolutionary life" book, "Born in Blood and Fire" and a couple others from the library...

Sorry if my English sucks lol. I found some websites, but they don't have much details on United Fruit company and the other U.S. companies that supported the dictator regimes in the South American countries...
I want to talk about the U.S.'s agenda and talk about why Che is good for going against the oppression set up by the US.

If anyone could help me with that thanks, if you can't that's okay too.
