Obama has escalated the drone wars. He has failed to extract us from Afghanistan and is putting our troops back into Iraq. 

"The U.S. on Monday launched airstrikes against the Islamic State (ISIS) in Libya, expanding its war in the region in what the Pentagon indicated will be a long-term offensive against the militant group and what critics said was a "deeply" concerning move."

Hillary Clinton is a well known foreign policy interventionist war hawk. Not only did she vote for the war in Iraq, she is responsible for talking a weak Obama into making war on Libya. If elected, we can expect Clinton to continue our foreign policy of perpetual war.
