This British Jihadist, Abu Rumaysah, told CBS News that one day America and Europe will be run by the Sharia and, of course, he called it a blessing:
Muslims believe that after the Mahdi comes, Jesus will return as a Muslim and will convince all Christians to become Muslims. He will do so by denying the cross ever happened and by denying the trinity. I suspect that this Muslim believes that if the Islamic State can’t bring the US under Sharia, that their Muslim Jesus will do it.
