Trump has promised to end the war quickly.
Donald Trump keeps his promises.
And, NATO membership is a deterrent against what Russia or any other aggressor country would do.
Russia hasn't been aggressor. Again, we promised Russia no eastward expansion of NATO and expanded NATO to its borders. Ukraine PLEDGED neutrality after the fall of Soviet Union and broke its promise.
Get this through your skull -- Ukraine will cease to exist before Russia allows it to join NATO. Russia considers a NATO military build up in Ukraine and grave threat to its national security.
And, given that Kaja Kallas and Duda have been talking about breaking Russia into six different countries, echoing a RAND study proposal, Russia has every reason to believe NATO in Ukraine is a threat to its existence.
