there has been a great change in the Arab culture from between the last 60 years since Israel settled its country in Palestine and since the invasions in the Arab world we are going to start country by country. first of all Morocco, Morocco has been one of the most Arab African countries with the less influence of assimilation, but still there has been a lot of assimilation in morocco when France invaded morocco they brought with them the french language and changed the pure Arabic language to a weird Arabian accent and Moroccan called (maghareba) Arabic have been assimilated from there traditional dress. Algeria is country said to be as the neighbor of morocco it also has been assimilated and invaded by France in world war 2 and France tried as much as it can to destroy the Arab culture in Algeria and convinced all the Arabs that they are french and that idea is still to today. Tunisia experienced the exact same thing which happened in Morocco and Algeria from France, but it was much worse and Tunisia is the second most assimilated Arab country in the world after Lebanon. Libya was invaded by Italy which had a way to bring the Italian language to Libya, except that Libya is a Bedouin type Arab non like other Arab countries so it kind of kept its culture and tribes, but still some assimilation in dress. Egypt has terribly been assimilated to western culture because of the wrong ideas and the Britain invasion of Egypt, Egypt in no way kept its culture and was lost for about 10 years. Syria and Palestine also has been assimilated because of the interaction with Jewish and Europeans in the middle east. Lebanon doesn't even count in the eyes of many Arabs as an Arab country because Lebanon was terribly assimilated from Arab culture by France from more than 90 years which is a record in the Arab world. Iraq was invaded twice once by Britain and once by America, but the Arab culture was not seriously affected because the Arab culture was really powerful at the beginning. in the Arabian gulf countries and Yemen the Arab culture was not influenced by anything and they kept there culture that passed on threw generations.
