I want to know the answer to the following question:
Who appointed Eisenhower as Supreme Allied Commander in Europe?
All the background I'm provided with is that "The following month, he resumed command of ETOUSA and the following month was officially designated as the Supreme Allied Commander of the Allied Expeditionary Force (SHAEF), serving in a dual role until the end of hostilities in Europe in May 1945.". Is that enough to answer the question?
