Honestly, I doubt it will happen, except in the case of a terror attack. Here's why: To launch a nuclear warhead would ultimately mean the free world as well as the majority of Earth's superpowers declaring mutual war on the initiating nation. Unless NATO or the UN agreed to use nuclear strength, but would that really happen? Not likely. Let's say that India or Iran launched one warhead in an attempt to devastate an enemy. Would the free world as well as the entire world stand for that? No, and more than likely military force would be used. A problem then is that the offending country may launch a series of warheads as a last ditch attempt to level the fields to a cease-fire. Scary thought. The odds of the US and any other nonproliferation country (including Russia, provided it is still under democratic power), to me are very slim. It seems as though the threat of global destruction would be too great a risk to include strategic warfare on the list of feasible military alternatives. I mean that in a sense of retalliation, as well. My point is, the world is more or less at a stand-off as far as strategic warfare is concerned. The only way I see a nuke going off in the near future (the world as we know it today) is from being in the hands of a terrorist or another form of extremist faction. The only question now is what will happen then?
