I think most within the CIA would be the first to point out that executing any Covert Action program that includes the arming and training of a foreign fighting force is a sketchy endeavor. Its also at the core of what the Agency was enacted to do, and takes its queues from its predecessor, in the OSS arming and training of resistance fighters during WWII. In short, this is not a new problem.
Given my nationality and experience, I can only speak about the American people and American military. In my opinion, we as Americans, have become so uptight that NO ONE can joke or have an opinion about anything without being ruthlessly attacked.
