So IOTL the eastern and western roman empires coordinated a large armada to retake North Africa for the western Roman empire, this did not go to plan and the result was a eastern empire without cash and a western empire doomed to fall.
However, what if this Armada succeeded? This would rejuvenate the western empire by reconquering a vital source of revenue and eliminating the vandals raiding the Italian coast. What would this empire look like? Would it be in a position to recapture most of the provinces? What would happen to the Ostrogoths, after all now they won’t be ‘invited’ by the eastern emperors to rule Italy for them.
