American foreign policy is like the Mystery Machine.
Conservatives get to drive, because like Fred, Daphne, and Wilma, they're the ones who have it together enough to operate a motor vehicle.
Liberals, like Shaggy and the Scoob, tag along, dreaming their sweet dreams of a better world they will never attain, and meanwhile constantly complaining about not enough food, too much scary, etc. Also like Shaggy and Scoob, the liberals run and hide, clinging to each other in fear, every time some sheet-draped asshat pops out and says "boo!"
Kim Jong Il has nuclear weapons? Quick! Run away and hide! Ignore the problem! Pretend it doesn't exist! If all else fails, try to appease the evil spirits!
Fred, Daphne, and Wilma, those uptight squares, are meanwhile working diligently to get to the bottom of the mystery and save the town/hotel/boathouse/whatever from the evils that beset it.
And Saddam Hussein is the old bastard saying "I would've gotten away with it, too, if it weren't for those stupid kids!"
