Gen. Clark's only talents are those important for someone wishing to become a General. Tell people what they wish to hear, flatter their intelligence by never contradicting superiors openly, and have a protective mentor more powerful then your competition and their mentors.
Clark was a nobody, going nowhere until he assisted at Waco. He made a powerful friend, and the rest is history. His smarts are the same as Bill Clintons. He can think a lot, but he cant DO anything.
