If one thing is clear after six months of fighting in Ukraine, it's that there is little chance of an imminent, overwhelming battlefield victory to end the war. Instead, the struggle has become (as expected) one of attrition and economics. A question of Russian economic resilience, matched against the will of Ukraine and its allies to carry on the fighting, and Europe's ability to endure rapid and deep cuts in the supply of Russian energy resources. In this 6 month update on the war, I focus not on the battlefield so much as the politics and economics of the war, and ask the question of how much pain is being inflicted, and if we should expect them to carry on in a way that winning a long war requires.
