What a weird thing to get upset at Lindsey Graham about. Hah. He was saying someone should step up to the plate and whack the modern-day equivalent of Hitler. What if Colonel Stauffenberg had succeeded? Could WWII have been ended more quickly?
Now, that would have unpredictable consequences, since Russia’s line of succession is poorly understood or nonexistent, and could cause a deadly internal power struggle, but it’s hard to imagine getting someone worse in charge of Russia than they have now.
The Ukraine War is Putin’s personal war by all accounts. Deposing Putin as a minimal-cost option is not an insane idea.
