I wouldn't put much stock in the assertions of this article -- they seem steeped in anti-Russian brainworms and cite no sources or specifics -- but this is the shit you stay up on if you're a "serious" Foreign Policy Expert. And the take it's running with today is "Russia is actually better at this than Ukraine now."
I honestly doubt it. I believe that everyone involved in backing Ukraine against Russia is going to be doing some variation of the "stabbed in the back" narrative. Western governments, Ukrainian civilian leaders, Ukrainian military leaders, Ukrainian soldiers, Ukrainian citizens, absolutely everyone is going to be pointing fingers and trying to deflect blame.
Of course we all know the real reason Ukraine will lose the war is because Russia's military was just plain better. Superior numbers, doctrine, logistics. This war was Russia's to lose, and so far they haven't.
