I dunno about you, but I'm resting pretty comfy with the knowledge China has these; as I see it the only downside is that chances are, Russia, North Korea, Iran, Yemen, and even the Palestinians and whoever else in the global south might desire them, does not also have them.
By all means, if the west truly cannot accept coexistence even with the promise of MAD hanging over their heads, and if they truly push things to WW3, then their slate (of "civilization," if unparalleled brutality and greed can be called that) should be wiped clean if you ask me. Such is deterrence, but frankly as someone living in the west it may as well also be considered a mercy, over leaving the survivors at the mercy (or complete lack thereof) of an unchecked western capitalist hegemony.
On one hand, yes. On the other hand, the overwhelming majority of people especially in the west do not start off progressive (at most some shallow facade of it), and their surroundings are inherently deeply regressive and reactionary.
She can and has to learn such basic decency and boundaries/moral or ethical convictions of her own accord, and that's a work in progress that takes time to figure out. Her environment and upbringing certainly isn't going to give it to her, rather the opposite...
I'm not giving her or anyone else a pass for being "fine with reactonaryism" (if this is the cause, which- well yeah, probably on some level). But understanding that it's a process of learning to be better, especially when living in the rotten core of all modern reactonaryism and evil, is just reality.
