Even more coincidentally, the article on occupation of Germany after WWI in "Army History" journal is followed by one titled: "Neutralizing the Hard Centre of German Militarism: US Military Government and the Wehrmacht's Elite Officers, 1945-1948".
In this article it states: "In March 1946, a new denazification law took effect in the US Zone of Occupation. Promulgated by German leaders but substantially influenced by American military government officials, the new law significantly changed the approach to denazification in the zone. Where previously American authorities had interned German civilians or removed them from influential positions largely on the basis of their membership in various Nazi Party organizations, the new law gave the Germans themselves primary responsibility for denazification... The new law placed less emphasis on excluding Nazis from German political and social life and more on evaluating, punishing, and rehabilitating individuals."
The article continues: "In the meantime, American and German reeducation initiatives had worked on the minds of the German people, and a dialogue on German history, the war, and the Wehrmacht had unfolded free of the voices of the many officers most passionately condemned by the Allies, and, it might be added, by their fellow citizens. Political leadership patterns were also established while they were unable to negatively influence German political life to the extent they had in the past.
Finally, American decisions ensured that when these officers (former high-ranking Wehrmacht generals and staff officers) did return home, they were reintegrated into German society and faced few lasting sanctions. In the end, the absence of tight controls may have well avoided creating a pool of aggrieved outsiders and so best served American interests. German veterans already felt defamed and abused, and the extent of pension activism suggests the stronger measures might have incited even more dangerous resentment and agitation."
Two very different approaches between post-WWI treatment of Germany (punish only) and post-WWII treatment of Germany (punish and rehabilitation). You tell me which one was more successful.
