No! Reagan’s plan was in effect until 1999 and we had peace. The plan, a buffer of non aligned states between NATO and Russia. Reagan saw a reunified Germany (yes, Mr. Gorbachev did tear down the wall) as the eastern most boundary of NATO. Had the incredibly destabilizing NATO hegemonists not rolled the greatest offensive military machine up to the Russian border, Russia would not have been forced into the counter escalatory move into Ukraine. Overthrowing the Uke government and placing a warmongering stooge satrap in power was the last escalation the Russians could tolerate. None of this would have occurred under Reagan.
So Reagan would have been okay with allowing Russian hegemony over Eastern Europe? Nope. There is NO DOUBT in my mind, that Reagan would have sent weapons to Ukraine.

Reality check to you, Reagan had the CIA fund the Polish Solidarity movement that helped overthrow the commie Polish government.
