Let's declare war on CO2 polluters. The largest polluters on the face of the earth:
China, US, Europe, India, Russia, Japan, Germany.
Nuke them, then might have a chance at correcting pollution production. If CO2 must be considered, then most efficient way to stop that is to nuke ourselves, since we are allegedly #2 on that list. Nuking, BTW, is the most efficient means of total warfare (using all available resources of a nation to actually defeat the enemy)--a strategy that has not been engaged in since WW2.
Otherwise, it is pointless to demand bankrupt Americans pay for something that other sovereign nations refuse to address in any real or valid or meaningful way. But then, if Islam comes to dominate the world as they claim they will do, FTW anyways.
