That's why I've been wondering if behind all this 'fog of war', Russia is planning to get what they want by creating a food shortage in Europe. Just toss a bunch of disposable soldiers and old equipment into the country, create chaos, and wait. Russia might survive the sanctions against it longer and better than Europe survives without Ukrainian wheat.
It sure sounds like Europe has a lot less leverage than Putin and might have to capitulate just to keep their people fed.
