I would give them fast track to join NATO or do the opposite in exchange for calling off Russian aggression.
The first diplomat who suggested that the Ukraine to join NATO should be fired, because it started the war.
Things where fine before that.
I thought that after 1986 that this cold war shit would be over.
I bet that NORAD will ask for a ballistic missile defense system would be installed in the artic again. Which will piss off the Russians even more.
