How an early Italian collapse transforms the Mediterranean

What is the largest Mediterranean consequence of France fighting on?

An early Italian political and military collapse could erase the historical North African war and open a new front against Germany.

French cooperation reduces Britain's need for Force H and the great Malta convoys while making an early loss of Italian North Africa more likely. Without the Afrika Korps campaign, Germany would have fewer reasons to commit forces to Italy and the central Mediterranean. If defeat in Libya coincides with reverses in Albania, Mussolini might fall before Germany can stabilize his regime. Italy could then become an Allied supply destination and battlefield, while the surviving Regia Marina helps protect traffic against German submarines.
