This testimony compilation is from the June 18, 2014 hearing before the Senate Committee on Environment and Public Works, Climate Change: The Need To Act Now." From the opening statement: "For several years now, our efforts have increasingly focused on consolidating the gains made over the past 13 years, and on empowering Afghans and Afghan institutions to deliver security, the rule of law, and vital services, including health, education, and economic opportunity, that all Afghans deserve. That is why we launched a process of transition in 2010, by which the Afghan National Security Forces have increasingly taken the lead role in protecting the Afghan people from insurgents who would turn back the clock on the extraordinary changes in Afghanistan. […] The timetable President Obama has laid out for Afghan self-sufficiency is a demanding one, but no more demanding than the transition already accomplished. Since 2011, NATO forces in Afghanistan have dropped from over 140,000 to 51,000 today, without occasioning any substantial loss of ground or population to the Taliban." Statements, letters, and materials submitted for the record include those of the following: James Dobbins, and Kelly E. Magsamen.
