I don't know why you're bringing BRICS into this. Brazil and South Africa aren't nuclear powers (at least not anymore, and South Africa is an irrelevant failed state anyway). India isn't engaged in any sort of ideological war with the West. Their nukes are purely defensive to deter China and Pakistan.

That leaves China and Russia. We learned during the Cold War that a policy of aggressive containment is effective and this should continue. Don't give them an inch.
