Great points. This is yet another "horseshoe theory" thing where the far-left isolationism aligns with far-right. Iraq was a clear mistake, but this time the end game is clear (Democracy-seeking patriots providing a buttress against expansionist/ruthless Putin), plus we have the luxury of sending support and not troops. I like the Spanish Civil War example, my late wife's grandfather jailed by Franco for resisting. US & others slow to grasp dangers of Fascism in 30s, but recovered nicely, Franco was then 30 yrs and out.
