Two good articles in Iraq, by Tony Blankley and by Thomas Friedman.
Best quote (from Blankley):
"Fighting and winning always impress. Even merely fighting and persisting impress. Shortly after the fall of Soviet Communism, I had dinner with a then-recently former senior Red army general. He told me that the Soviets were astounded and impressed by the fact that we were prepared to fight and lose 50,000 men in Vietnam, when the Soviets never thought we even had a strategic interest there. They thus calculated that they'd better be careful with the United States. What might we do, they thought, if our interests really were threatened?"
