< Only the Muslim leadership is clever and they claim that the Quran is not to be taken literally and it's all up for interpretation, and muh liberal Andalusian utopia etc.
However what they cannot control is the main Muslim part and the true believers who won't wait. So shit will go down ever more. When the countries go 15-20% Muslim then you will see massive immense violence, far more rape and terrorism. AT levels of 25-30% you will likely need the military in the streets and rivers of blood after some prayers at the mosques. So no - they won't wait 60 years, because that is not their thing.
