Bi-Partisan Solution to Iraq?

I propose that we treat the problem like one big oil spill. The world cleans up the mess. The U.S. triples its troops. Every other country in the world provides a significant amount of troops. We blanket the place with soldiers. Baghdad - 7000 soldiers per square Kilometer, minimum. We don't let anyone kill each other. Drastic steps, but I'm talking maybe 5 million troops from all over the world shoving peace down their throats. The troops stay till the killing ends. Agree or Disagree?
