Huntington argues that the Islamic civilization has experienced a massive population explosion which is fueling instability both on the borders of Islam and in its interior, where fundamentalist movements are becoming increasingly popular. Manifestations of what he terms the "Islamic Resurgence" include the 1979 Iranian revolution and the first Gulf War. Perhaps the most controversial statement Huntington made in the "Foreign Affairs" article was that "Islam has bloody borders". Huntington believes this to be a real consequence of several factors, including the previously mentioned Muslim youth bulge and population growth and Islamic proximity to many civilizations including Sinic, Orthodox, Western, and African.
