WASHINGTON — NATO allies are in final negotiations over language that says Ukraine’s eventual admission into the military alliance is “irreversible” − so long as it makes a series of reforms required for membership.
The U.S. and other member nations agreed at last year’s summit in Lithuania that Ukraine would become a member “when Allies agree and conditions are met.”
This week they are likely to acknowledge at a critical summit in Washington that, while Ukraine still has a ways to go, as long as it continues to make progress, there will be a path to NATO membership, a U.S. official said.
NATO Secretary-General Jens Stoltenberg told reporters Sunday evening in Washington, D.C., that allies are close to agreeing on precise wording.
