Wednesday's HOT MIC
Lead and they shall follow.
The most important two Arab states are Egypt (population) and Saudi Arabia (wealth), and neither seems likely to retaliate beyond a pro forma protest. Saudi Crown Prince Mohammad bin Salman can't afford to derail his modernization effort by emboldening a bunch of reactionary hotheads, and Egypt can't afford to do much that isn't bankrolled by the Saudis.
The Iranian Mullahs were going to do their mullah thing regardless.
Turkey however remains the wildest of wildcards...
