The main issue is NATO. If Nato leave the Ukraine and doesn't make any deal with Ukraine so the Russia will skip the War. And if it continues so the crisis will never end.
The trouble is, if NATO left today, the war wouldn't stop today. It would take a little while for Russian police action to make sure of Russia's safety, and Ukraine's safety from the Nazi militants.
And there would still be the question of equitable dealings regarding the land that the 3 big American companies bought from Ukraine, and some of the 46 American backed, Wuhan-style labs that Ukraine has. Some of might have been legal, and still might be legal.
