I think that the first point is a legitimate one - if your own government can buy you, so can someone else. Of course, when it comes down to it, everyone has a pressure point. In my thoroughly uninformed opinion, it would be better to identify and protect against such tactics than do them yourself and watch it backfire like this.
The rest, I can't argue with, though it doesn't really make me feel any better.
