Who The Hell is John Bolton?

This from a lobbying website "The Center for American Progress" I found on google...

"He has been called a "treaty-killer" and a "guided missile." He is known as the "undersecretary for chads" and the "anti-diplomat."[ii] Recently he called concerns over how many nuclear weapons North Korea possesses "quibbling." [iii] And, former Sen. Jesse Helms thinks of him as "the kind of man with whom I would want to stand at the gates of Armageddon."[iv] And, if President Bush has his way, John Bolton will now answer to the title of U.S. Ambassador to the United Nations

Though many on the left of the aisle do not agree with his views, few can claim him as incompetent. Indeed, Bolton has been effective: in his first one-and-a half years in office the U.S. pulled out of the Anti-Ballistic Missile treaty with Russia, scuttled a protocol to the biological-weapons ban, ousted the head of the organization that oversees the chemical-weapons treaty, watered down an accord on small-arms trafficking and refused to submit the nuclear test-ban treaty for Senate ratification.[xv]

At this point it is clear that the world Bolton has left us four years later is one that is more dangerous. He can only do more damage from a position of greater power."
