Pentagon doesn't label Russia as the enemy, U.S. Defense Department spokesman John Kirby said during a May 26 briefing.
"Nobody's labeled Russia the enemy. I know you did. But that's not the phrase that we would use to refer to Russia," Kirby said, commenting on Serbia's joint military exercises with Russia.
"And I would let these two sovereign nations speak to their exercises and bilateral relationship, that's really for them to speak to," he added.
