russia has done this big call—up, they're preparing thousands of troops for the spring. what else do you think they could do to tip the balance back in theirfavour? the most vulnerability the ukrainians have is their access to nato weaponry. so i don't think the russians have done it terribly well. in fact, in many ways, they've done it in a counterproductive way. but what they need to be able to do, if they're going to have any chance to weaken ukraine, is to try and cut that supply of weaponry. and that's a political task. and i think that's the only way they can materially affect the course of the war in terms of really weakening ukraine. i'm less convinced of these attacks on civilian infrastructure. i mean, they can certainly make a difference because they divert ukrainian attention, but on the other hand, they're not decreasing ukrainian will to fight, they're probably increasing it, so i'm not sure that that's going to have the effect that they think.
