I think the higher powers of the European and communist countries are promoting control of CO2 to take down the US economy. Notice how militant environmentalists are about it? It's because they have been conditioned to act that way, and that's by design.
I thought you'd put all that stuff behind you? "Commie" countries, I assume you actually mean China? They pollute worse than the US do, so I can't see it being them starting it. A few EU countries did play their part, but TBH I think it's more some tree-hugger/greenie agenda than trying to take out the US economy. They're militant, 'cos they're the noisy minority, like anti-abortionists, gaybashers, religious extremists etc...
