I'm talking about the many possibilities. I'll talk about it in any way you choose to frame it. And I've already given my opinion that Russia's use of a tactical nuclear weapon would most likely not bring a full scale nuclear response by America.
Or, it 'would' bring a full scale nuclear response from America, if you like?
But of course the scenario I wouldn't entertain is that Russia will accept defeat and so if there is a significant nuclear response by America on Russia, there wouldn't be the obvious in return.
If you really want a grownup conversation with me, you can frame it any way you like.
I don't see much point.
