"Ambassador Blackwill's career as a Foreign Service Officer began in 1967, after a stint in Africa with the Peace Corps. During 1979-80, he served on the NSC Staff as Director for West European Affairs. In the early 1980s, he worked at the State Department as Principal Deputy Assistant Secretary, first for Political-Military Affairs, and then for European Affairs. From 1985-87, he was US Ambassador and head of the US Delegation to the NATO--Warsaw Pact negotiations for reduction of conventional military forces in Europe. This article is based on the author's interviews during 1991-93 of Ambassador Robert D. Blackwill."
