I think that it's a curse that we have found ourselves in a land unsuitable for a sedentary lifestyle. Thousands of years of nomadism has left us with customs and personal characteristics ill suited to keep up with the demands of modern civilization. All nomadic countries are small, weak, economically wretched and as a result find themselves under the heel off more powerful sedentary neighbours.
As for Greater Somalia, at the moment it's hopeless and useless to ponder about it as priority is stabalisation of somalia.
I think Somali maritime history exciting so far as trade with the rest of the world was concerned.
