Could anyone suggest a book that exposes the true nature of Guevara?
More and more i'm coming across people wearing those shirts and I'd like to have a better understanding on what he really was about.

Boy all you gotta do is corner any Marielitos and they will tell you, but here is a good book that will tell you anything you need to know....

Thanks for the quick reply.

If he was a product of his genes then perhaps his relatives would have been involved in the IRA and ETA (he was Basque + Irish mix).

However, I suspect his time in the USA probably lead him to adopt the American position of Unionism (I bet his ancestors groaned in their graves):
From Wiki:
("By trip's end, he came to view Latin America not as collection of separate nations, but as a single entity requiring a continent-wide liberation strategy. His conception of a borderless, united Hispanic America sharing a common 'Latino' heritage was a theme that prominently recurred during his later revolutionary activities)".

Thus he adopted the worst American stereotypes of his own peoples.

I also know that studying to be a doctor is incredibly boring and incredibly time consuming, I can well imagine young Che wanting to do anything else apart from being a blinking medic!! Something much more IMMEDIATE!

He didn't really have the brains/patience to see that to get rid of South American fascists you did not need Communism ( a QUICK LAZY solution), what you needed was capitalists breaking down "fascist red tape" over long decades until no government works apart from Capitalism. He was lazy.
