Normandy? Normandy!

The title is a quote form one of the many confused Germans in The Longest Day, a movie I recently panned in this space.

One alternate history scenario...

After the failure of the Normandy landings Eisenhower was sacked and replaced by Montgomery, who felt his strategy of caution and overwhelming force had been vindicated.

With the invasion threat removed, Hitler was able to shift more than a dozen divisions, many of them his best, to the Eastern Front, where sudden counterattacks by the likes of the 2nd and 12th SS Panzer Divisions blunted the Soviet offensive and saved the German position in the east. Lines settled around the old Polish-Soviet border.

As stalemate ensued in both east and west, President Roosevelt was defeated in the election of 1944. In January of 1945, President Dewey fulfilled his campaign promise to concentrate on the Pacific and by April of that year, Curtis Lemay's 20th Air Force bombarded Japan on a nightly basis, blockaded and facing starvation.

Japan, now isolated and withered, President Dewey looked for a way out of the European morass, especially now that rumors abounded that Stalin was looking for a separate peace. Fortunately, that summer the army showed Dewey a way out of the European mess via the new super weapon it had built in the desert.

The Allied nuclear bombardment of Germany began in August with the destruction of Hamburg and three days later Wilhemshaven, both chosen in reaction to the renewed German submarine threat. Even as the Americans third and last bomb was dropped on Bremen, planners wondered if future attacks should not be made in the east to aide the Soviets, who alone were able to drive on Berlin and end the war...
