Welcher Politiker steht für die "Ostverträge"?Which politician is associated with the 'Eastern Treaties'?

Explanation

Willy Brandt, as Federal Chancellor from 1969 to 1974, initiated the policy of Ostpolitik and signed the 1970–1973 “Ostverträge” with the USSR, Poland, Czechoslovakia and the GDR. These treaties acknowledged post-war borders and aimed at détente and cooperation between East and West, making Brandt the politician most closely identified with them.
