This makes NO sense.

Just because the top hegemon would think to ask Russia to cut ties with North Korea - would Russia have heartily agreed?

Well here is the answer:

And for the top hegemon to put such a request is asking to be snubbed by the Russians.

I cannot believe that the top hegemon likes being humiliated.

Is the American taxpayer really happy about a thing like this.
