Sure, I can start. You've highlighted one key area, that the alliance is looking to respond to an increasingly tense situation. As of 2014, with the invasion into Ukraine-Crimea, we've seen the largest increase in forces associated with NATO since the Cold War. It's in direct response to the threats that Russia has posed to international peace and security. I'm not looking at it from the nuclear aspect, but it's all related.
Deterrence is not simply having one nuclear capability able to challenge another nuclear capability; it's a spectrum of operations that goes from conventional forces to nuclear forces. NATO, through its Reassurance efforts, is actually increasing its deterrent capability in the European theatre. That deterrent capability is directly focused on the instability in the international community caused by Russia's activities. I hope that answers your question.
