Carl Bildt, former prime minister of Sweden and co-chair of the European Council on Foreign Relations, shares his perspective on European politics from Tabiano Castello in Italy.

How will the Ukraine Kursk incursion affect Putin's way of handling his war?

No question. It does complicate things for him quite considerably. First, they were trying to say, "Well, this is a quick thing. This will be over. The mighty Russian army is going to throw out the evil Ukrainians within a short period of time." That has clearly not been successful. So, now they're trying to say, "Well, this is not a big thing." They're trying to play it down. But whatever. It does complicate significantly the narrative that Putin has been trying to hand out, some say, or get anchored with the Russians that victory is going to come. It's only question of patience. He will have quite considerable difficulty. More on the political way. In the political respect than in the military with this operation.
