WASHINGTON, D.C.—President Obama has no choice now. If he wants to defeat ISIS, he’ll have to become a real war leader. He may not like it, but putting troops on the ground is the surest way to win this war.
That’s nothing new. Paris was horrific, but no game-changer. The game changed in 2014, when ISIS broke out from Syria, drove the Iraqi military from the field and proclaimed a worldwide caliphate.
