tldr: the cia and state department are legally required to share what they've done in the past 25 to 40 years and the stuff they've released so far shows a well documented history of the american government giving weapons, money, mercenaries, etc. to any organization that is the self declared enemy of a progressive movement that's going left.

in this context, it means that they're referring the parts where the cia gave money to italian and spanish letists -- anarchists in this case -- that caused political violence in western europe to prevent their governments and people from becoming "too progressive".

have you not heard of the cia? they've funded most nazi paramilitary groups in all of history. operation condor much?
