I usually stay out of these kinds of discussions, but felt compelled to add my two cents.
The US has been the unofficial "police" of the world for several years now. Not only that, but we also pour millions of dollars (and resources) into war-torn countries trying to help them get back on their feet. We are even on the verge of paying damages to the ancestors from our slavery days, but that is a topic for another discussion.
If other countries don't want to support us in a "show of force" to stop a madman, then I say, let's take our tanks, airplanes, food, and money back; and put it to good use in our own country to help employ, feed, and protect our own people.
It is unfortunate that we waited so long before contemplating taking action. Sometimes, that makes it even more difficult to justify. I think the biggest fear (and possible explanation) is that the Vietnam Conflict was so unpopular and everyone is afraid of history repeating itself.
I'm done now.
