If you think things between the U.S. and Russia are cozy, think again. Pentagon officials say two Russian aircraft buzzed a U.S. Navy warship in the Arctic’s Barents Sea last week, each coming within about 50 yards of the frigate. Flying by Navy ships in international waters is not unheard of. But this Cold War-style incident was enough to stir some concern. Pentagon spokesman Col. Dave Lapan said Navy personnel aboard the ship did not believe the actions were hostile. He told reporters on Friday that the U.S. was still trying to determine whether either side broke protocol.
