Effect on Europe if Carthage won the Second Punic War?

For that sake of simplicity, let's assume that Rome loses by failing to adopt the strategies of Fabius Cunctator, of deliberately avoiding pitched battle with Hannibal long enough for the army to recover. Hannibal is able to keep up the pressure with battle after battle, and a fractured Roman elite is unable to offer or appoint a steadying hand to stop the people and other cities from calling for peace.

What happens to this Rome that admits defeat, and the Carthage, and Hannibal, that inflicts it? What are the longer-term effect on the continent as a whole, with the probable dominant power on the mediterranian being a primarily sea-based power in North Africa rather than a land-based on in Italy?
