Mediterranean sea..

One hypothetical question came to my mind today, If you look at the Mediterranean south shore, Arab countries of north Africa from Egypt to Morocco have a much longer coast with this sea than any other ethnicity such as Italians, French or any other European country. Now if based on that fact, these Arab countries start calling it Arabian sea and teach that in their school books and put in their treaties, would National Geographic or any other organization in Europe or North America dare to change the name?
