Concessions made to minorities have increased and Turkey today faces a serious problem. Unfortunately, the meaning of multiculturalism has been misunderstood on both sides. Nation states should think deeply about the crisis of multiculturalism and should make radical decisions if they want to continue their existence. It should be noted that due to mishandling of multiculturalism, the Ottoman Empire was blown up by its own bomb.
