The vice president has made an unannounced visit to Kabul "to assess progress toward the transition to Afghan-led security beginning this year, and to demonstrate the United States’ commitment to a long-term partnership with Afghanistan." Biden will meet with Afghan President Hamid Karzai and visit the Afghan National Army Training Center. His visit comes at an odd moment for Afghan security. While Obama says that Afghanistan's progress is on track and that Taliban groups in the south are under control, there are still insurgent troops within the country and in Pakistan. Afghanistan is also under heavy corruption within the government and Biden has asked President Karzai to address this major hurdle. Meanwhile U.S. military officials are waiting to see what kind of insurgent activity will resume in the spring to get a better assessment of Afghanistan's security progress.
