NATO leaders would invite Ukraine to join the military alliance “when the Allies agree and conditions are met,” NATO Secretary General Jens Stoltenberg told reporters Tuesday as NATO begins its annual summit in this Baltic nation. Stoltenberg’s comments came after Ukrainian President Volodymyr Zelensky had criticized NATO leaders. In a tweet, he said, “wording is being discussed without Ukraine” that gives little clarity on his country’s prospects for joining the bloc, in apparent reference to draft text that had been circulated. Kyiv wants specific pledges on when and how it can join the defense alliance.
