As for your alleged "duplicity", Vlad the Invader is arguably the most brilliant Russian, and he was not "duped" into anything, much less into invading Ukraine twice!GWB gave Putin parts of Georgia, Obama gave him Crimea, and Biden is giving away Donbas. I've tested it with Heinlein's razor, but it can't even be explained by stupidity. I'll stick with duplicity, as candor is entirely lacking from the U.S. government.
None of those presidents "gave away" anything, what they did was refuse to go to war with Russia, or even seriously oppose Vlad the Invader's foreign conquests.
They did what Neville Chamberlain & Co did in the late 1930s, in the Rhineland, Austria & Sudetenland -- they appeased the Russian bear.
You may remember that Winston Churchill blamed Neville Chamberlain for WWII, saying, if Chamberlain had followed Churchill's advice to get tough on Hitler, then the Second World War would never have started.
But that's a far cry from ludicrously claiming that Chamberlain himself started WWII.
Whatever the failures of Chamberlain, GWB, Obama or Obiden, the morally responsible agents were Hitler and Vlad the Invader.
By the way, I'm a big fan of Robert Heinlein's science fiction books, read them all when I was a boy, and there is no doubt whatever that Heinlein used a razor on his bald head.
But the razor I think you're talking about belonged to a 14th century English Franciscan friar named William of Occam, in southern England.
Friar Occam didn't use this particular razor to shave with, but rather as philosophical tool, to help chose among competing explanations for, say, a physical phenomenon.
