Look - Russia is the ultimate loser in this war. They were supposed to conquer Ukraine with "shock and awe" in a matter of weeks, not get bogged down in a 3+ year war. They've lost nearly a million men and their equipment has either been destroyed or exposed as sub par. It will be a decade or so before Putin or his successor could even contemplate a serious invasion of another county. All they've gained is the Donbas region, which will require billions or trillions to rebuild.
For this I give the Ukrainians a TON of credit. They've fought like no other ally of the US has fought using our equipment since the Russians in WWII.
