Paul is making the point that there is NO Iraqi navy or air force to speak of, they have not shot down a single plane in the 12 years since we lost the Persian Gulf War and the army is a 1/3 the size it was when we fought them last.
Oh yes he is making that point, but he making that point when Moyers asks about the dangers of Sadaam attacking the U.S.
Perhaps we need to replay the exchange in slooow motion for you to read the piece more closely.
MOYERS: Have you seen or heard anything from the CIA, the Pentagon, the State Department or the White House to suggest that Saddam Hussein is planning an attack on the United States?
Uh ... okay. What does Moyer's framing of the question have to do with the substance of Paul's reply and how is it that the question somehow negates the prong of Just War that is defending against aggression?
