Madsen has gleaned through some recently released CIA documents (heavily redacted, of course) to discover that various operations under their control have been going on since at least 1953. This corresponds with other information that has been uncovered regarding the efforts of the nascent Empire using both soft weapons of propaganda as is described in this article and more terrorist type organizations such as Gladio (example, Operation Gladio--see this and this) which was used to rig elections, infiltrate, and crush leftist organizations and unions all over Europe and nearby areas.
Although he does not furnish any references for his analysis, I have long held this independent journalist as one of the best. No one is infallible and above criticism, but I consider Madsen as one of the most reliable and qualified sources of information and analysis regarding government secrecy. I've only found very minor errors such as his claim that Asst. Sec. Victoria Nuland spoke to Congress about the $5 billion dollar support of subversive efforts in Ukraine. I've been able to find that she only made this claim to the National Press Club (7:42m).
