Will Joe Biden Be Right?

It looks like Joe Biden may be right about a major issue for the first time in his ever long career; President elect Obama could be tested by an international crises, namely an armed conflict between nuclear arch-enemies Pakistan and India. Great.
The main thing that makes a nuclear exchange between these two nations seem unthinkable, is that the repercussions are too ugly to contemplate. That doesn't mean it can't or won't happen. We live in interesting times.
