There is a common bond: language. Language binds a people. It also separates them.In the Bible we see the story of The Tower of Babel.
The people were united in one language but because they became 'ambitious' God Babeled them. From here we see Babylonia. He separated them by language groups.
The study of languages, linguistics, deals with problems in languages. Semitic is part of the Afro-Asiatic language family. People who speak these languages stretch from Africa to Asia.
Some are the Ethiopian languages such as Tigrinya , Amharic and Oromo. Arabic, Egyptian Coptic, Berber, the list goes on and on. The Table of Nations in Genesis 10 is the best place to start in order to understand the human family, and all its diversities.
I hope this helps. Sorry its taken so long but I am back at University. I have been extremely busy...
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
