Im not saying nuclear war is inevitable, just that its a risk that shouldnt be ignored. If things escalate too much both countries could get paranoid that the other is preparing a preemptive strike. When you look at the US and Russia, there is an understanding that neither country benefits from a first strike because both nations possess the ability to strike back. Thats probably a big reason the Cold War ended without a nuclear catastrophe. What if Russia didnt have that capability? Things might have ended differently, and we werent even fighting each other. This situation with Pakistan and India should make people nervous. Hopefully, tensions ease and things die down after a bit. Thats probably the most likely outcome, but still – having a not insignificantly greater than 0% chance of a nuclear strike is very worrisome.
