There was no such thing as the United Nations. You are confusing the League of Nations with the UN. Germany was in the League for a short time in the 1920's but withdrew in 1933 when Hitler became Chancellor.

Germany was divided into West Germany and East Germany. The United Nations were formed and United States and Soviet Union emerged as two world powers. The two world powers began the cold war.
The League of Nations never "became" the United Nations. The League of Nations was formed as a result of World War 1 and fell apart as the world moved into World War 2. During the War, those national with which the US and Britain were allied were often called "The United Nations." After the War, in 1946, a formal organization called The United Nations was created, but it was not a continuation of the old League of Nations, which had been discredited by its inability to respond to the increasing belligerency of Germany and Italy.
