And he should.

Nuclear power is not entirely safe. Nothing is. But yelling Cheynobyl whenever Nuclear power is discussed is plain stupid. It was an unsafe design, and do you know why it went wrong? The engineers turned off all the saftey features, and ran it over design limits, to see what would happen.

If you want to cut CO2 emmissions, then there are a few things you could do.

Build some Nuclear power stations, or

Convince the country it doesn't want its cars, A/C units, etc, or

Get the rest of the world to cut CO2 emmisions. Nuking it back to the stone age would do, or

Decide you don't mind rising sea levels. We don't mind Louisiana, Bangladesh etc being underwater...

One other thing. The two larest sources for nuclear fuels are North America, and Australia. I'd rather send money there, rather than the Middle East.

I will say this slowly:
Just because it's Bush doing it , it doesn't have to be wrong.
