Carl Bildt, former prime minister of Sweden, shares his perspective on European politics from Stockholm.

What's going to happen after the horrible terrorist attack in Moscow?

Well, obviously, the Russian authorities have great difficulties with it. The US gave advance warning that something could happen in Moscow. It was repeated by several other embassies. That was publicly dismissed by Putin. And, of course, Putin is saying that all of the danger that is there is Ukraine and the West. Nothing else. He has everything under control. And then suddenly, well over 100 people dead. And evidently the security authorities responding fairly slowly. So he has now to adjust his narrative.
