FILE - In this Jan. 23, 2010, file photo, U.S. Vice President Joe Biden, left, meets with Iraqi Prime Minister Nouri al-Maliki in Baghdad, Iraq. A burst of strength by al-Qaida that is chipping away at the remains of Mideast stability now confronts President Barack Obama, testing his hands-off approach to conflicts in Iraq and Syria at the same time he pushes to keep thousands of U.S. forces in Afghanistan. The U.S. withdrawal at the end of 2011 was followed by a spike in sectarian violence and most recently, the alarming takeover of two cities by an al-Qaida affiliate known as the Islamic State of Iraq and the Levant.
