There's already talk of uprising(s) in Algeria and Morocco. I'll be honest, I have very limited knowledge of the region (very confusing to ever study and truly comprehend) but I reading that the East of Libya is the oil rich portion while the West (Tripoli) is not and is completely different. And yep, it was put together during the 20th century, so a definite power vacuum would exist.
It's just a very interesting time and I wish for the safety of all involved. The only other time I can think of such wide-spread uprisings looking to overturn the governments in place would be the 1848 revolutions in Europe.
