WASHINGTON (AP) — President Barack Obama vowed in the State of the Union address Tuesday to relentlessly hunt down terrorists from "Pakistan to the streets of Paris," then called on Congress to approve new war powers against Islamic State militants. Obama argued that U.S. military leadership in Iraq and Syria is stopping the Islamic State's advance, but asked lawmakers "to show the world that we are united in this mission" with a war authorization vote. "Instead of getting dragged into another ground war in the Middle East, we are leading a broad coalition, including Arab nations, to degrade and ultimately destroy this terrorist group," Obama said in remarks prepared for delivery.
