Paul Nitze, an experienced politician and long-time presidential advisor on defense policy who had participated in the SALT talks, led the US delegation after being recruited by Secretary of State Alexander Haig. Though Nitze had backed the first SALT treaty, he opposed SALT II and had resigned from the US delegation during its negotiation. Nitze was also then a member of the Committee on the Present Danger, a firmly anti-Soviet group composed of neoconservatives and conservative Republicans. Yuli Kvitsinsky, the well-respected second-ranking official at the Soviet embassy in West Germany, headed the Soviet delegation.
