After 2014, we will support a unified Afghanistan as it takes responsibility for its own future. If the Afghan government signs a security agreement that we have negotiated, a small force of Americans could remain in Afghanistan with NATO allies to carry out two narrow missions: training and assisting Afghan forces, and counterterrorism operations to pursue any remnants of al Qaeda. For while our relationship with Afghanistan will change, one thing will not: our resolve that terrorists do not launch attacks against our country.
