The 2016 presidential campaign is well under way, and the candidates are already jousting over who is best suited to respond to an increasing number of obstacles abroad, ranging from the refugees crisis in Europe and the Middle East, to the threat of ISIS, to Russian aggression under President Vladimir Putin. As Democrats and Republicans, the four of us will almost certainly support different candidates in November 2016. But we all agree on this: Our security and prosperity are at risk if America retreats from our leadership responsibilities around the world.

There could not be a riskier time for America to pull back.
