American Libertarians. Unlike you, I am an American, not a foreign agent. With that said, if the Ukrainians can defend their homes, so be it, and I wish them well. Unfortunately, there are only three realistic possibilities as to how this ends.
1. A partial Russian victory, in which an indefinite stalemate occurs, with Russia keeping most of the territory they invaded.
2. A total Russian victory, in which Ukraine becomes a rump state, and only that, because Russia doesn't actually want to annex a hostile population at their back.
3. World War with NATO intervention.
I get that your preference is No. 3, although I am not sure why. My own preference is that Russia simply withdraws, but that's not realistic.
