They're not really getting destroyed, cuz Ukraine has't advanced a single kilometer into Russia, plus out of 3 million available soldiers they only use around 100 thousand which is less than 3%, and even if something goes completely wrong: they have 6000+ nukes which is enough to turn Ukraine (and most of the world) into ocean
Not trying to be nerdy or anything, just saying that it's too early to judge the winner
Although you can think whatever you want
