Here is just a tidbit of what Newt said:

WASHINGTON (CNN) -- Former House Speaker Newt Gingrich blasted the
State Department Tuesday for a series of what he described as
diplomatic failures leading up to the war with Iraq, and warned that
the pattern is poised to repeat itself.

In a speech delivered at the American Enterprise Institute, a think
tank in Washington, Gingrich contrasted the experience of the State
Department with the Defense Department. He said the State Department
had failed in its efforts to apply diplomatic pressure to persuade
Iraq to disarm and comply with U.N. resolutions, and it is time for
"bold, dramatic change" at the department.

"The last seven months have involved six months of diplomatic failure
and one month of military success," said Gingrich, who sits on a
Pentagon advisory committee. "The first days after military victory
indicate the pattern of diplomatic failure is beginning once again and
threatens to undo the effects of military victory."
