MIKE BARNICLE: "What would you do about Aleppo?"
GARY JOHNSON: "And what is Aleppo?"
BARNICLE: "You're kidding me? Aleppo is in Syria, it's the epicenter of the refugee crisis."
JOHNSON: "OK, got it, got it," Johnson cut him off, and then added, "With regard to Syria I do think it's a mess. I think that the only way that we deal with Syria is to join hands with Russia to diplomatically bring that at an end."
"It's just a mess."
