When taken in a direct 'wordish' translation, the Sea of Middle Earth, is the Mediterranean Sea. Likewise many maps see this Sea of Middle Earth as a European Sea, by usually cutting off Africa and Asia. Rather is a Sea of Unity between Asia, Africa and Europe. Yes! Asia is a part of Mediterranean Sea culture!
Nonetheless Tunisia has certain amount of area reserved for her economic exploitation. Such that, no other nation may fish, harness, or collect the natural resources of the area, unless permitted so by Tunisia. Yet this part of the world is not a part of Tunisia, thus it is a weird kind of twilight area.
