With all the opposition from the French and Germans, and the fifth column media in the U.S., the political pressure to assume that we had "won the war" and put our heads in the sand would have been overwhelming.

Terrorism comes from the middle east, specifically Saudi Arabia and Iran. Taking Iraq into our camp alters the situation from a gradually deteriorating one for us to one with a strong chance of improvement over time.
