Bali: US vision versus EU caution

So the cautious Europeans have got their concensus on carbon emission cuts after all.
I expect that there are some on the American right who rue the European refusal to let the Americans handle climate change their way.
After all, only a generation ago wasn't the biggest challenge to the global climate posed by the threat of a nuclear winter?
So why not think outside the box and go for a win/win solution here?
I'm surprised that none of the Neo-Con think tanks has suggested that as Mr Bush has the technology, as well as the military hardware, the most elegant way to offset global warming would be with a few localised spells of nuclear winter. In, let's say, Iran, North Korea, and (should Cuba be a bit too close for comfort) maybe Venezuela.
Not only would that avoid having to take any tiresome steps that may well lead to an economic slow-down, but it would keep the world free for global exploitation - whoops! er, I mean... 'democracy'.
