I don't think they will launch a war in the traditional sense. Too expensive, especially with the rate of devaluation that is attached to fiat currencies. Let's not forget the level of civil unrest (and potential conflict) that will cause. Cyber and drone warfare will become the new widely adopted means to wage international conflicts. I mean, we're already seeing that increasingly become the case since it's a cheaper, more profitable form of warfare.

You're definitely right to be worried about things going nuclear, though. It's a scary thought to think that one of our silos could get hacked into.
