That is a matter to be concluded between the United States and Afghanistan. It is a pertinent question. The answer will depend on the definition that those countries together have for their future strategic partnership. Of course, the long-term presence of United States forces is a controversial subject in the region. The matter has not been settled. I stress to my hon. Friend the growing size and capability of the Afghan national security forces, which are building up to a total of 352,000. They are equipping themselves extremely well in the current conditions.
