From 1993 to 1999. Pryce served as a senior official in the Office of the U.S. Secretary of Defense, first as Special Counsel for International Affairs and then as the senior policy advisor to the Under Secretary for Policy. In the former position, he negotiated over a dozen nuclear disarmament agreements with Russia, Ukraine, Belarus and Kazakhstan. As Counselor to the Under Secretary of Defense for Policy, his responsibilities included formulation and articulation of U.S. international security policy in the interagency process, congressional testimony, speeches and public statements. He was particularly involved in policy and diplomacy regarding European security, including the Balkan conflicts, U.S.-Russia relations and NATO enlargement; multilateral negotiations with international security implications; and critical regional security issues such as those arising in Haiti, Iraq, and North Korea.
