Are We Going to Blow the World Up Using Nukes?

We're seeing the russians be a lot more aggressive around the corral islands, which are islands that they contest with japan. And we've seen this alliance between china and russia, where they described each other as having an unlimited partnership,. That was about the time of the olympics. However, now, all of a sudden, the chinese quickly backing away and trying to take distance from Russia. We have basically no response to hypersonic weapons - so is there a need to create kind of circuit breakers? How far can we push this person? I'd say again, talking is a whole lot better than finding out.
