If Afghan leaders and the White House can't agree on a key security pact, the U.S.-led alliance will pull all of its troops and equipment out of Afghanistan by December, NATO's secretary general said Wednesday. According to AP, the announcement from Anders Fogh Rasmussen at the start of a NATO defense ministers meeting ratchets up the pressure on Afghan President Hamid Karzai to strike a deal. On Tuesday, US President Barack Obama threatened to withdraw all U.S. troops from Afghanistan by the end of 2014 if the pact isn't signed.
