The question would then be could Russia without nukes resist the Chinese? Russia might have to decide between allying and truly normalizing with the West (which doesn’t really want or need to subjugate Russia, it just wants Russia to behave no worse than, say, Brazil does in S. America), or being mostly eaten by China.
Tough choice. The former requires Russia to reject a good part of its historical mindset, the latter loses it most of its territory.
