>Besides, the world could become a better place the day the wahhabism oil-funding fades and vanishes.
Instability and collapse in Saudi Arabia or the wider Arab world would be good for nobody, even if it's inevitable. Lack of oil funds isn't going to make Wahabism go away or reduce the threat it poses, in fact IMHO quite the opposite. A triumphal raised finger in that direction is likely to get bitten off.
I wish them to be busy working for a living and to have no money to waste abroad buying a place in heaven for their princes by building salafist or wahhabit mosques. I do not wish them to collapse as a country... Even if the transition from black-gold to hard working might be very difficult.
