The dude is clearly delusional, as are his followers.
The better comparison is Neville Chamberlain in how he will turn a blind eye to the aggression of a despot; "peace in our time." Chamberlain led the effort to allow Nazi Germany to annex Czechoslovakia, which of course turned into additional Nazi aggression in Poland, starting WWII. His encouragement to Putin to invade a NATO ally could not be more clear.
