Berlin lies more than 100 miles behind the Iron Curtain within the Soviet-occupied zone of Germany. It is not, however, part of that zone. It is a separate political entity for which the four major allies of the war against Nazi tyranny are jointly responsible. Its special status stems from the fact that it was the capital not only of Hitler''s Third Reich but of the German nation formed in the latter half of the 19th century.
