My book titled Bending Spines: The Propagandas of Nazi Germany and the German Democratic Republic (Michigan State University Press, 2004) provides an analysis of much of the material on the German Propaganda Archive. It can be ordered in the United States through amazon . It is also available in a French translation. A Chinese edition appeared in July 2012 but was almost immediately banned by the Chinese government (but not in Hong Kong). It has since been “unbanned.”
Until the conclusion of the Battle of Stalingrad on 2 February 1943, German propaganda emphasized the prowess of German arms and the humanity German soldiers had shown to the peoples of occupied territories. Pilots of the Allied bombing fleets were depicted as cowardly murderers, and Americans in particular as gangsters in the style of Al Capone . At the same time, German propaganda sought to alienate Americans and British from each other, and both these Western nations from the Soviet Union. One of the primary sources for propaganda was the Wehrmachtbericht , a daily radio broadcast from the High Command of the Wehrmacht , the OKW . Nazi victories lent themselves easily to propaganda broadcasts and were at this point difficult to mishandle.  Satires on the defeated, accounts of attacks, and praise for the fallen all were useful for Nazis.  Still, failures were not easily handled even at this stage. For example, considerable embarrassment resulted when the Ark Royal proved to have survived an attack that German propaganda had hyped. 
As West Germany was reorganised and gained independence from its occupiers, the German Democratic Republic was established in East Germany in 1949. The creation of the two states solidified the 1945 division of Germany.  On 10 March 1952, (in what would become known as the " Stalin Note ") Stalin put forth a proposal to reunify Germany with a policy of neutrality, with no conditions on economic policies and with guarantees for "the rights of man and basic freedoms, including freedom of speech, press, religious persuasion, political conviction, and assembly" and free activity of democratic parties and organizations.  This was turned down; reunification was not a priority for the leadership of West Germany, and the NATO powers declined the proposal, asserting that Germany should be able to join NATO and that such a negotiation with the Soviet Union would be seen as a capitulation. There have been several debates about whether a real chance for reunification had been missed in 1952.
