Adenauer's view that Stalin's offer was not serious was widely shared. However, there were other views about how to react to the offer. The Minister of All-German Affairs, Jakob Kaiser, had a "bridge theory" which suggested that Germany could be the mediator between the East and the West. He agreed with Adenauer about the importance of free elections and the refusal of the Potsdam borders, but Kaiser took the Soviet offer very seriously. In a radio address on 12 March 1952, he stated that the note had an important political significance, but he still thought it was important to approach it with caution. He asked for the Soviet suggestions to be carefully explored so that no opportunity for reunification would be missed.
