The difference is now probably going to be made by the weapons flowing into ukraine from the west. We've seen evidence, for example, that french caesar artillery systems are coming in. The big issue for the coming days is whether america will send something called multiple launch rocket systems. These are rockets that can fire in large amounts over longer ranges. And so i think this could make a substantial difference on the battlefield. I think that this is very much not the end of the story, and isot given the way things are.
