Does anyone here have a problem with the idea of stopping the spread of communism?

I think the real question is not "Does anyone" but "Did anyone". Stalin was vigorously opposed to the Marshall Plan. It was not in the Soviet Union's perceived self-interest although in the long run, the US's position was proven correct. For that matter, it was not in the perceived self-interest of Germany in WWII to capitulate to the Allies. Which is somewhat analogous to the situation now in Iraq. The Iraqi government desperately feels it is not in its interest to lose the war (although it will inevitably). It remains to be seen whether the Iraqi people can (like the Europeans including Germany did) build from this loss into something better than they have today. I think the US feels the Iraqi people can do so.
