if saudi arabia tried to totally isolate itself form the rest of the world economy then 1) they would get invaded and 2) they would ecomically collapse, and 3) the riba economy will still survive without saudi arabia. So you cant pin the worlds ill on saudi. And ikhwan and saudi are the best we have at the moment. Do you criticise turkey also? What about tunisia? What about yourself? Do you pay tax? Do you own a bank account? Do you purchase from shops which are part of the economy? So arent you also supporting this system?
