Highly doubtful. This thing will likely drag on for years unless something unexpected happens. Russia has been doing a piss-poor job, but they still have plenty of natural resources and people to throw in the meat grinder. The sanctions are bleeding them, but they still have plenty of oil to sell and there’s plenty of buyers still. Plus, if the Republicans and other Russian-compromised groups in other countries are able to get their way, they’ll cut off foreign support to the Ukrainians.
