Fourth World War: Chinese spy trashed 'Blue Team' skeptics: "Ronald Montaperto, the veteran Defense Intelligence Agency officer who spied for communist China, also served as an agent of influence to destroy the credibility of scholars and policymakers who saw the PRC as a threat to national security.
As a member of the Blue Team that follows Beijing's military and intelligence operations, this blogger saw firsthand how Montaperto would malign the arguments, presentations, facts, credibility and integrity of US intelligence officers and mid-level officials who warned of PRC intentions and capabilities.
Montaperto was so pro-Beijing that Blue Team members half-joked among themselves that if he wasn't a recruited agent of the PRC, he at least acted like one."
This is another time when I'm cribbing a whole (small) post. however, if you follow the link and return to Waller's site, he's got a lot more on Montaperto.
