“Nixon’s Back Channel to Moscow: Confidential Diplomacy and Détente,” by Richard Moss.

Most Americans consider détente to be among the Nixon administration’s most significant foreign policy successes. The diplomatic back channel that national security advisor Henry Kissinger established with Soviet ambassador Anatoly Dobrynin became the most important method of achieving this thaw in the Cold War. Richard A. Moss’s penetrating study documents and analyzes US-Soviet back channels from Nixon’s inauguration through what has widely been heralded as the apex of détente, the May 1972 Moscow Summit. He traces the evolution of confidential-channel diplomacy and examines major flashpoints, including the 1970 crisis over Cienfuegos, Cuba, the Strategic Arms Limitations Talks (SALT), US dealings with China, deescalating tensions in Berlin, and the Vietnam War.
