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

How is the role of NATO evolving now as the 75th anniversary of the organization coming up?

Well, it's going to be Ukraine that's going to be defining the future of NATO. Two issues most immediately: One, if NATO can take on a stronger role for coordinating military aid to Ukraine, that's been done so far by an ad hoc coalition and US support; there’s a proposal on the table for taking that over. The second is, of course, what Secretary General Jens Stoltenberg proposed on the day of the ministerial meeting in Brussels, to set up a very large fund for financing the military support in the years to come. We'll see how these two proposals evolve over the time period up until the Washington summit. And then there's, of course, the big issues of Ukraine membership.
