There are two "coalitions" operating in Afghanistan, one of which has a strict basis in international law. The "US-led coalition", identified by the press, refers to Operation Enduring Freedom, mostly special forces, air and naval forces, within a strictly US chain of command, exercising over a wide international geographic area, the US right to "self defence" accorded by the UN charter. The "NATO-led coalition", identified by the press, refers to the forces of the International Security Assistance Force (ISAF) led by NATO, with a specific United Nations Security Council mandate within Afghanistan, including most of the US forces in Afghanistan, NATO contingents and some non-NATO forces. (Note that in many articles within Wikipedia and elsewhere, this distinction is confused).
