Russia will fight a war of attrition, Putin has little concern for Russian lives. Ukraine can not win a war of attrition. The pace of the war needs to be stepped up in the Spring. In the meantime the West needs to give Ukraine the weapons and training needed to quickly bring the Russians to their knees, come Spring. And that means precision long distance strikes at military targets inside Russia, Crimea and at sea, and a virtually impenetrable air cover over Ukraine. The least expensive and most efficient way to bring this war to a close is to greatly step up the pace of assistance to Ukraine. Russia can only win this war if it becomes a drawn out war of attrition. That must not be allowed as an option for the Russians.
