NATO invited Montenegro to join its ranks, 16 years after the U.S.-led military alliance bombed the Balkan country in the Kosovo war. NATO’s 28 foreign ministers met Wednesday for a two-day meeting in Brussels and extended the invitation—its first expansion in six years. NATO Secretary-General Jens Stoltenberg has called the invitation a “historic decision.” The bid is likely to fuel tensions with Russia, which has repeatedly warned against expansion as a threat to stability in the western Balkans.
