I understand what you are saying, and it really wasn’t directed at the “insurance” type gameplay you just explained. It’s more referencing the flexing done by apeman and kosmo in recent times, threatening moves with nukes - not conventional warfare. The war system does not favor sitting around and building so many nukes. It allows people with more cities to hit you at your inflated score, you can’t really downdeclare, and you don’t even do full damage with the new war types. There is almost no benefit to hoarding stocks of nukes other than to use it as a scare tactic.
