Jonathan Tobin has an excellent article this week in Israel Hayom on why the moderate Muslim states are more beholden to the radicals on the street than they have influence over them. However, there is one thing that they could do that would counter the narrative that drives the street radicals. That would be to promote the teachings of Ibn Taymiyya regarding Jerusalem.
This should be natural for Saudi Arabia because Ibn Taymiyya is the unassailable authority for Saudi Arabia on everything else. However, politically, the Saudi government might not be able to promote Ibn Taymiyya's views on Jerusalem at this point. However, if individual Saudi clerics were to do so, the government could plausibly deny any role in calling for yielding on Jerusalem. Would it be worth asking those who conduct discreet talks with the Saudis to ask them to green light imams to write about Ibn Taymiyya's views of Jerusalem, using the same language that Ibn Taymiyya used for today's Muslim visitors to Al Aqsa and the Dome of the Rock?
