Bolton -n- Westermann

Mr. Ford's gruff, direct and sometimes off-color manner took some
senators aback, as when he described Mr. Bolton's dressing-down of Mr.
Westermann by saying that "he reamed him a new one."

Such a statement begs the question 'what was wrong with his old one'?? But perhaps that is beside the point.

Senate Foreign Relations Committee, Carl W. Ford Jr., who was
assistant secretary for intelligence and research, said Mr. Bolton
was a "kiss-up, kick-down sort of guy" who "abuses his authority
with little people," and an ill-suited nominee to become ambassador
to the United Nations.

This John Bolton character doesn't seem like a very nice fellow and so not a good pick for a head diplomat-guy to the U.N. So, I looked up diplomat on dictionary.com, you know, just to check, and this is what I found.

One who uses skill and tact in dealing with others.

I really don't think he qualifies.
