Racial Theories in Fascist Italy Book

Where does all the money come from to pay for the expensive safe houses, multiple trips between Colombia, Paraguay, Brazil, Nicaragua, and Cuba... the food, the hotels, the weapons?

This book reads like a thriller, but Alegria and Flakoll are purposely leaving out key details to paint their revolutionary "heroes" as ideologically pure. I suspect that the real truth is more complicated and that understanding the funding of the operation would create a very different nonfiction novel.
