In literature on diplomacy, the term Ostpolitik refers to the new foreign policy of the Federal Republic of Germany introduced in 1966. The policy, was initiated by the grand coalition of the Christian Democratic Union (CDU), the Christian Social Union (CSU), and the Social Democratic party (SPD) and was continued after 1969 by the SPD and Free Democratic party (FDP) coalition. The policy aimed at reconciling Germany with Poland and the Soviet Union. Willy Brandt, the SPD foreign minister from 1966 to 1969 and chancellor from 1969 until 1974, and Walter Scheel, FDP foreign minister from 1969 to 1974, were the architects of this new “selective Détente.” From the beginning, Brandt's Ostpolitik was “controlled” by the Nixon administration, especially by Kissinger. The United States feared that Brandt and Scheel would go too far without taking account of Washington's geo-political point of view.
