(CNN)Secretary of State John Kerry insisted Sunday that a recent spate of terrorist attacks reflects that ISIS is "on the run" in Iraq and Syria. Kerry downplayed attacks like the shooting at an Orlando nightclub, a driver's rampage through a crowd in Nice and the Istanbul airport attack, saying they don't reflect the strength of the group in its home bases. Those attacks "the desperate actions of an enemy that sees the noose closing around them," he told CNN's Jake Tapper on "State of the Union."
