Italy all comes down to what UK does against your fleet.
All three transport survive: No British player in their right mind would allow this but if this happens, going after Egypt is a must.
Two transports survive: Safe UK move, usually Italy tries to make a move in Africa or at least go after neutrals.
One transport survive: Italy normally abandons Africa and focus on Can Opening for Germany
No transport survive: I am pretty sure this is impossible with OOB version, maybe a bid could make it doable but again, without any transports. Go to Can Opening for Germany.
