It is unlikely that the new heir to the Saudi throne, Prince Mohammed bin Salman – who will be the first of King ibn Saud’s grandchildren to come to power – will stop the private Saudi program of promoting Salafism. Salafism is the radical form of Islam practiced by the Saudis, and their export of their beliefs has been a major cause of the Muslim world’s move towards radicalism over the last nearly 40 years. But the Saudi leadership might respond to a US suggestion that they begin to omit Indonesia and India from their program. This would protect a critical quarter of the world’s Muslim population from moving from moderate to radical Islam.
