BM What do you think would be the final goal for the Kremlin at this point? What would be considered a successful outcome for the invasion?

SK I don’t know what the outcome of this war will be, but I think it will involve the partition of Ukraine, one way or another. Hopefully there would still be something called Ukraine left at the end. But Russia cannot afford to “lose”, so we need a kind of a victory. And if there is a sense that we are losing the war, then I think there is a definite possibility of escalation. This war is a kind of proxy war between the West and the rest – Russia being, as it has been in history, the pinnacle of “the rest” – for a future world order. The stakes of the Russian elite are very high – for them it is an existential war.

BM You talked about demilitarisation of Ukraine, but it seems that such a goal would not be achieved if the West continues to provide Ukraine with weapons. Do you think Russia will be tempted to stop that flow of arms, and does this risk a direct clash between Nato and Russia?

SK Absolutely! There is a growing probability of a direct clash. And we don’t know what the outcome of this would be. Maybe the Poles would fight; they are always willing. I know as a historian that Article 5 of the Nato treaty is worthless. Under Article 5 – which allows a state to call for support from other members of the alliance – nobody is obliged to actually fight on behalf of others, but nobody can be absolutely sure that there would be no such escalation. I also know from the history of American nuclear strategy that the US is unlikely to defend Europe with nuclear weapons. But there is still a chance of escalation here, so it is an abysmal scenario and I hope that some kind of a peace agreement between us and the US, and between us and Ukraine, can be reached before we go further into this unbelievably dangerous world.
