The CIA is making "declassification" of archived documents about their various activities... so there will be definitely proofs of the USA being involved in supporting dictatorships on other countries or promoting "golpe"... there is a lot to know about the "greatest democracy in the world" misdeeds and I invite anyone to know about it.
This is about the revealed documents:
