This isn't a proxy war. Russia is invading Ukraine because they want to invade. That has absolutely nothing to do with anyone else; Russia is not a proxy.
Ukraine has exactly one choice: defend themselves, or be subjugated and killed. There is no diplomatic solution. It's very helpful that Ukraine has outside help. But that doesn't make it a proxy war. Regardless of whether or not Ukraine had outside help, they'd still be fighting.
The fact is that the #1 thing Ukraine is doing right now to win is destroying Russian industry with Ukrainian made weapons. They're doing that themselves. Again, that's not a proxy.
