"Had Brandt not taken the lead in ‘normalisation’, other powers would probably have done so. At the same time, West German governmental and, to some degree, public complicity in the East German regime increased alongside engagement with it. This complicity was displayed both by Brandt’s SPD successor, Helmut Schmidt, the Chancellor from 1974 to 1982, and by the latter’s CDU replacement from 1982, Helmut Kohl. Complicity, however, may be an inappropriate as well as harsh judgment, as little would have been achieved by upholding the Hallstein Doctrine and continuing to refuse to enter into dialogue with East Germany. Moreover, the change in policy brought real relief in the form of visiting rights and family reunifications, not to mention buying ‘regime opponents’ out of jail."
