For that to happen, Turkey has to show that it is true to Islam. There is no country on earth today which is true to Islam. The ones who were true to Islam, have been devastated by War. And Turkey that the Ottoman Empire will not ever come about, ever again. Instead of dreaming about the Ottoman Empire, it should be aspiring to unite Muslims and forge strong alliances with Muslim countries such as Iran and Pakistan.
There was a time when this almost happened with the RCD. Pakistan, Turkey and Iran were poised to establish trade routes, bringing the three countries together, closer in people to people relations and country to country relations. There was a time when we thought as Muslims, not as nationalists. We can still achieve this, only we can learn to crush our differences and work toward a positive and strong future.
