Their motives are corrupt. The Ukrainians putting it on the line have pure motives, but they are only getting help because the corrupt people helping them stand to benefit from their success and Russia’s defeat. Zelensky is a go-between, and the conflict is not about him, but about the Ukrainian People and Putin. He helps them fight, both by being their spokesman and symbol, and also their head schnorer.
The fact that these a@@-holes are gushing over him is a good thing, because it means weapons on the battlefields and aid for starving and hurting people. But I have very little patience with gush-y people, even where I might agree with them in part. Even so, I will gush for Trump. But that’s a choice based on experience. The gushing over Z is an act by people so phony they don’t know how to not act and pose.
It's brutally obvious but, well, see my tagline.
