President Obama made a surprise trip to Afghanistan Tuesday night, vowing to “finish the job” and saying U.S. troops will not stay “a single day longer” than necessary. Marking the one-year anniversary of the high-stakes raid that killed al Qaeda mastermind Osama bin Laden, Obama said, “This time of war began in Afghanistan, and this is where it will end.” Obama and Karzai signed the “strategic partnership agreement” to outline the cooperation between the two countries after NATO’s withdrawal of forces in 2014. After Obama’s exit, at least three explosions rocked Kabul, and the Taliban immediately claimed responsibility.
