Almost at the end of Kleiber's career there was a debacle after he accepted an invitation to resume his pre-war post at the Berlin Staatsoper. Following the post-war division of the city, the house was in East Berlin. The old building had been bombed and was slowly being restored. In 1951 the East German authorities invited Kleiber to become musical director when the rebuilding was complete. At the time, hostility between the Soviet bloc and the western allies was intense, and some ardent democrats thought Kleiber wrong to work for the totalitarian East German régime. The Berlin Philharmonic Orchestra withdrew his invitation to conduct at its concerts, but he felt he was building bridges between east and west. The reopening was scheduled for 1955, but as the time approached, Kleiber became increasingly aware of state interference in the running of the house. Matters came to a head when the authorities removed an old monument to Frederick the Great that was a key feature of the building. Kleiber wrote, "I have had to acknowledge that the spirit of the old theatre cannot reign in the new building", and he resigned before the re-opening. Feeling that the West Germans had been mean-minded in their attempt to stop him conducting in East Berlin, he left the city and never returned.
