Later and current Arab Nationalist leaders include Muammar al-Gaddafi of Libya, Hafez al-Assad and Bashar al-Assad of Syria. The diverse Arab states generally maintained close ties but distinct national identities developed and strengthened with the social, historical and political realities of the past 60 years. This has made the idea of a pan-Arab nation-state increasingly less feasible and likely. Additionally, an upsurge in political Islam has since led to a greater emphasis on pan-Islamic rather than pan-Arab identity amongst some Arab Muslims. Arab nationalists who once opposed Islamic movements as a threat to their power, now deal with them differently for reasons of political reality.
