Part of NATO’s discussion:

Estonia is calling for Nato to abandon its “tripwire” posture in eastern Europe and build up a permanent force in the region capable of stopping a Russian offensive.

Ahead of Thursday’s Nato summit, Jonatan Vseviov, the permanent secretary of the Estonian foreign ministry, said that Europe and the North Atlantic alliance could never return to the world it knew before the 24 February Russian invasion of Ukraine.

“We will be in a totally new security environment. There will be a new Ukraine. There will be a new Russia. There will be a new Europe. There is no going back to February 23,” Vseviov told the Guardian in an interview in Washington.
