Let's be fair! There are many arabs in Europe and the states, and most of them carry professional degrees. Now why on earth I shouldn't trust those guys back in my home country. As far as governments are concerned, they only look for those promising minds to stay and make a living. The eye surgeon who has done the op to one of my relatives in UK was a fantastic young specialist from Egypt who has lived and worked in there for years, and I still admire his attitude and knowledge so much. May be we don't encounter lots of similar examples, but in the end there will never be any good reason for imposing the generalization of ideas!
