How would Allied control of Tunisia affect Malta and Italian North Africa?
Short answerIt would simplify Malta reinforcement and make the Italian position in Libya far harder to sustain.
NotesFrench North Africa changes Malta from a carrier-ferry problem into a much shorter land-based staging route. Fighters could move between friendly airfields along the North African coast, rest in Tunisia, and make the final crossing to Malta the next morning. That route reduces reliance on elaborate carrier operations to deliver replacement aircraft. At the same time, Italian Libya would face pressure from British forces in Egypt and Allied forces advancing from the west.
