It doesn't seem like it but, we are probably very close to World War 3. All it takes is one spark and with NATO and Russian forces so close to each other, with just the borders of countries separating them, one small mistake, an errant missile that hits unintended target or even just an armed skirmish and it quickly escalates. Consider too that a cornered animal is very dangerous. Tactical nuclear weapons could end up being used by both sides. Not talking about ICBMs initially but, a nuclear warhead could be attached to missiles, bombs, howitzer rounds and have such destructive effect. The fallout will be horrendous too because intense radiation will be spread in the conflict zone including, other countries not even involved in the conflict zone. And if the shooting does not stop, doesn't matter. We will all be dead. This is a time when cooler heads needs to prevail. A political solution is needed. Escalating the situation just brings us that much closer to World War 3.
