The capacity, transparency, and legitimacy of Afghan governance are considered crucial to Afghan stability after U.S.-led NATO forces turn over the security mission to Afghan leadership by the end of 2014. The size and capability of the Afghan governing structure has increased significantly since the Taliban regime fell in late 2001, but the government remains weak and rampant with corruption. Even as the government has struggled to widen its writ, President Hamid Karzai has concentrated substantial presidential authority through his powers of appointment at all levels.
