Strauss was appointed minister of the treasury again in 1966, in the cabinet of
Kurt Georg Kiesinger. In cooperation with the
SPD minister for economy,
Karl Schiller, he developed a groundbreaking economic stability policy; the two ministers, quite unlike in physical appearance and political background, were popularly dubbed '''', after two dogs in a 19th-century
cartoon by
Wilhelm Busch. After the SPD was able to form a government without the conservatives, in
1969, Strauss became one of the most vocal critics of
Willy Brandt's
Ostpolitik. After
Helmut Kohl's first run for chancellor in
1976 failed, Strauss cancelled the alliance between the
CDU and CSU parties in the Bundestag, a decision which he reversed only months later when the CDU threatened to extend their party to Bavaria (where the CSU holds a political monopoly for the conservatives). In the
1980 federal election, the CDU/CSU opted to nominate Strauss as their candidate for chancellor. Strauss had continued to be critical of Kohl's leadership, so providing Strauss a shot at the chancellery may have been seen as an endorsement of either Strauss' policies or style (or both) over Kohl's. But many, if not most, observers at the time believed that the CDU had concluded that
Helmut Schmidt's SPD was likely unbeatable in 1980, and felt that they had nothing to lose in running Strauss. Schmidt's victory was seen by Kohl's supporters as a vindication of their man, and though the rivalry between Kohl and Strauss persisted for years, once the CDU/CSU was able to take power in 1982, it was Kohl who became chancellor. He remained in power well beyond Strauss's death. ==European integration==
