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

How is the process of accession of Finland and Sweden to NATO going?

Well, it's green light for Finland. After ratification by Hungary and Turkey, they've been playing some games, but now green light. Good, excellent. Sweden, they are still holding out. I think President Erdoğan sees this as an asset in his election campaign. There have been some issues with Sweden. I think they have been sorted out, but now it's a question of the politics of Turkey. President Erdoğan, of course, faces an extremely critical election May 14, first round his entire regime's up for grab, and he's holding Sweden hostage in a way that is not entirely good for the security of Europe.
