Relax.

If there's a nuclear war, every half-way decent sized city in the world will vanish within a few hours of each other. If you live in a city that's been bombed, you might not even notice you've been bombed because the signals might not have time to register in your brain before you die. For all intents and purposes, about 54% of the world's population (city dwellers) in an all out nuclear exchange will die a very speedy death, leaving the remaining 46% (the rural inhabitants) having to endure a few days of radiation sickness before they die.

Conventional warfare lasting years or decades is much scarier. Can you imagine the on-going life of a six year old Syrian child from 2011 to now? Scary. Or a Yemeni 10 year old now? Scary.
