I think I figured out what your sticking point is. You completely lack knowledge of what nuclear weapons are and how they work. You seem to have this idea of nukes as some mythical all-destroying force. You seem to think that once a country develops nukes it instantly has the power to flatten Washington DC or New York, and can start dictating terms to everyone.
> No country that has built nukes has ever built "just a few dinky nukes" - so you are imagining a world that doesnt even fit objective reality.
Actually that's exactly what India, Pakistan, and North Korea did.
The reality is that nuclear weapons development is expensive and hard to hide. No nation has ever successfully hid its nuclear proliferation activities. Every nuclear-armed country has gone through a phase when its nukes were pretty crap and ineffective and it was vulnerable to attack and takeover by other countries. Ultimately, the reason such intervention didn't happen had nothing to do with the fear of nuclear retaliation from those nations.
I'll grant you that (B) is a good argument and the first non-psychopathic thing you've said so far. And it shows that you're simply not listening, because I'm mentioning a global non-proliferation effort that would by definition marginalize rogue states that attempted to develop nuclear weapons.
But I get it. People like you don't want peace. You want war. You'll come up with pseudo-scientific bullshit to support your cause in any way you can. Nukes are necessary, you'll say, right up to the point where some fool presses the button and we all have to deal with the radioactive consequences.
