Tony Karon writes: President Barack Obama used the broadest of brushstrokes on Wednesday night to describe his “comprehensive strategy to degrade and ultimately destroy” the Islamic State insurgency, providing few details and skirting discussion of key dilemmas facing any such plan.

The United States will lead a “broad coalition,” Obama said, but its war plan “will not involve American combat troops fighting on foreign soil.” Instead, the campaign would rely on U.S. air power and support for “partner forces on the ground” to put the Islamic State (IS) to flight.
