Can global warming prevent a new Cold War?

It seems President Bush is tap dancing on a nuclear landmine with Russia. First, talks of putting missiles at strategic locations around the former Soviet Union, then a comment that Russia is backsliding on it's democratic reforms. With the US war on terror in full swing and those two issues out in the open, I'm guessing that Russia probably fears becoming a renewed enemy of the US. I can smell a new arms race brewing, especially when you toss in the now infamous speech by President Bush several years ago.
