On last night's show, columnist David Goldman joined me to discuss Saudi Crown Prince Mohammad bin Salman's efforts to halt the flow of Saudi money to Islamists abroad.

With China and Russia increasing their presence in the Middle East, the Saudi Crown Prince (assisted by the United States) is working to halt the flow of money to Sunni Muslim extremists in those countries. The move comes at a time when the Crown Prince is attempting to consolidate his power domestically and mend relations with regional powers.

I worry that these efforts will fail the same way attempts to combat Saudi Islamists have failed in the sixteen years since 9/11
