119. Other negotiations are taking place on issues which have threatened peace in Europe since 1945. There is the recent treaty between the Soviet Union and the Federal Republic of Germany", and the Federal Republic's negotiations with its other neighbors to the East. They hold the key to constructive coexistence in Europe. 120. The test, of course, as always, is not in words but deeds, and in that area Berlin is still the key to real coexistence. If we cannot agree to take the humanitarian step of lowering the barriers between two halves of a city, what hope is there for two halves of the European continent to live in peace? Berlin therefore will be the touchstone of the will of the peoples of Europe to achieve detente between East and West, It was in Berlin that the ordeal of 1939 to 1945 ended for Europe; and it is in Berlin that Europe is still waiting for a release from the aftermath of war and the beginning of a peace which is real.
