United States color-coded war plans (English Wikipedia)

Fleming, Thomas (1987). "The Big Leak". American Heritage. 38 (8). If Hitler had stuck with his original decision and acted to frustrate the objectives of the Victory Program, he could have freed a hundred divisions from the eastern front for a Mediterranean offensive. [This] could have turned the Mediterranean into a German lake and frustrated the Allied plan to seize Africa and attack Europe from the south. The catastrophic German defeat at Stalingrad would never have occurred, and the Allied attempt to invade Europe at any point, particularly across the English Channel, would have been much more costly.
