I'm not sure how any of the above relates to the matter under discussion, but...

Global Research is a known fringe nut-job conspiracy site, and its credibility is something less than zero.

I'm not in a position to know why the Peace Corps pulled out of Kazakhstan, but a fast and complete pullout is usually a result of a real or suspected threat to volunteer safety.

The Peace Corps is actually a pretty useless tool for espionage. Volunteers and staff are typically well to the left side of the political spectrum, quite allergic to anything even vaguely resembling military or intelligence involvement, and are likely to howl to the media at the first hint of an approach... as that complete ass in Bolivia who tried an approach discovered to his chagrin. It would certainly be possible to insert an agent without the knowledge of the staff of other volunteers, but as anyone who's been a volunteer or has been close to the organization knows, it wouldn't be a very useful cover.

It would be silly to deny that espionage takes place, but it's equally silly to attribute all one sees to espionage, especially when far more likely explanations are at hand.
