What would be our goal in doing that? How would we define success, or failure? Are will willing to go to war if the ante keeps increasing? This not some distant neutral corner of the world but Russia's own border, so total war would be on the table with Russia's existence threatened. If we aren't willing to go all the way then we should not go at all. Our strength would be diluted by overreach, and our stature would be further diminished by half-measures and failure. And economically, waging a major war in our newly weakened state would be catastrophic to the US Dollar.
