Britain's route back into Europe without America or Japan

If Japan and the United States stayed out of the Second World War, where would Britain launch its main amphibious return to Europe?

Through the Mediterranean: defeat Italy, land in southern Europe or southern France, and keep Germany distracted by a threatened northern landing.

In the scenario with Japan outside the war, Britain would avoid a Far Eastern campaign and could concentrate its attention on Europe. The proposed route begins in North Africa and advances through Italy, where naval power could support operations aimed at forcing Italy out of the war. A landing in southern France is then suggested as a possible next step. Britain would retain a northern threat to keep German forces watching the Atlantic Wall while the main advance came from the south.
