All this bloodshed and misery and the US will still end up losing the fight. Russia had a reasonable demand to not have NATO on its doorstep. Finland and Sweden (until just recently) were examples of the fact that Russia isn’t willing to attack a neutral nation.
That’s it, at the beginning of the war, Blinken could’ve just offered Ukraine’s neutrality (and possibly guaranteed independent protections for Donetsk and Luhansk) in exchange for Russia paying reparations. That would’ve been reasonable, but the US doesn’t do anything reasonable.
