Jeff, your plan of action makes sense. Though, I wonder at its consequences. Once, it would've been certain to cause Putin and Russia to halt in place. Now, though, it's only a probability -- maybe 75-80%.
Because, if Putin continues to impinge on Ukraine, say, in the Donetsk, there's not a damn thing we or NATO can do about it. Only the Ukrainian forces in the field would have any credibility.
The question would still be how far does Putin want to push it?
The Ukrainian army is terrible and poorly trained and equipped. They’re not going to fight the Russians for the Ukrainian Nationalists. The Western Ukraine Bandera Nazis are the ones who want war with Russia and have been preparing for this since World War II ended.
