i agree that nuclear disarmament and nonproliferation is dead. and clearly it is the case that countries that do not develop nuclear weapons will not enjoy westphalian sovereignty as they did for the previous few centuries, but it's not clear that westphalian sovereignty in the nuclear age was the stable equilibrium that it was in the gunpowder age, and now drones have probably made nuclear weapons obsolete, with so-far-unforeseeable consequences for the contours of international relations
it's possible that pursuing the will-o'-the-wisp of westphalian sovereignty under those circumstances will just make the situation worse and increase the chances of human extinction, which (i feel safe in saying) would be a worse outcome for poland
