I suggest, to do what the US always does, expect THIS TIME IT WOULD BE JUSTIFIED...
INVADE and TAKE OVER Saudi Arabia.
This time it would be easy and could even succeed.
Saudis are lazy and extremely low iq, their fighter jets are from USA which can shut them down if needed, pilots are foreigners who just fly for money (same allegiances as with whores = they would run home as soon as first missile hits mecca). There are also no outside powers who would support S-A as they have turned everyone against them.
Their weapon is, however, the moskues they are funding in the west which preach hate against white people - there are plenty of lunatics waiting for orders in those places. I think this is what Americans are afraid too.
