eh, you gotta die of something. A nuclear fireball is probably no worse than a nursing home and a six-pills-a-day medication schedule.
Seriously though, I can’t see any nuclear war happening. Even if NK actually has a few fission bombs, it is theoretically possible to knock them out on launch. There’s no way of knowing how this is likely to pan out, but NK is nowhere near as powerful as they like to make out. If any war happens, China will almost certainly lend tacit support to make sure it happens efficiently. I really can’t see them attempting to sabotage a Kim takedown. The CCP are assholes too, but they’re well aware of the economic and PR consequences of wars, IMO.
