WASHINGTON (AP) — It’s not as clear as President Barack Obama made it sound Wednesday night that he has the authority to go after Islamic State militants in the manner he plans, with sustained airstrikes and associated military actions designed to neutralize the foe. What is clear, though, is that he’s going ahead with it anyway.

In his speech to the nation, Obama also said his strategy against militants operating in Iraq and Syria calls for no U.S. troops in the fight, but it’s not that simple.
