Assalamualykum.
Brother Osama you are a very knowledgeable Muslim. You have sufficient knowledge in Arabic, Science, History and also about world politics. So, I think you should obviously write some books or magazines explaining these subjects in the light of Islam. May be then more people will come in touch with Islam. So brother, write some books or open a TV channel which will have broad discussions on the above subjects in the light of Islam. It will help us in Dawah. And people (Muslims, Christians, Jews etc) will get to know what Islam is and why it is the only religion acceptable to Allah.
Take Care.
