If the British take Tripoli before the Afrika Corps can be despatched

- lets say through
an earlier British offensive or avoiding despatching forces to Greece
whatever
-

it may not be possible for the Axis to land a force in Libya to retake Tripoli.

Hitler might abandon supporting the Italians in Libya.

Might siezing Malta become more important.

Might they sieze Tunis - summer 1940 - if they do, does this require the occupation of Vichy if indeed the Germans have the forces to do so - if Barborossa has begun. Might it forestall Barborossa if not.
