American losses? No chance, the Russian army is not even in their league. As for Ukrainian and Russian, they are not playing tiddlywinks, war costs lives.

You'd think having had occupiers on your doorstep you'd actually have a bit of sense and sympathy about you, I'm sure you'd have been fine with us Brits razing Ireland to the ground, which we could have done if we were that way inclined.
