The GOP is having a foreign policy fight

A real fight is brewing ahead of the 2016 Republican presidential primaries. It’s a war over the way the last GOP administration waged the war on terror. The question to be settled: Is this still George W. Bush’s party?

For a while, it looked like these divisions might be papered over. Rand Paul seemed to be soft-pedaling some of his less interventionist positions, moving closer to fellow Republicans on the Islamic State and Iran. Then many of the other candidates admitted the Iraq war was a mistake, at least in hindsight, including usually reliable hawks like Marco Rubio and Chris Christie.
