Turkey can be roughly divided in two: Istanbul and the rest of the country. Istanbul is the role model for all Turkey. Turkey emulates Istanbul. It doesn’t matter whether it is political, cultural, social, economic, sports, whatever. There are two prerequisites for any trend to be adopted by Turkey: To originate from Istanbul or to be approved by Istanbul. Any trend that is not adopted by Istanbul is bound to remain ineffectually local.
Istanbul is the key junction of the country. Istanbul decides who passes through that junction and who can’t. Therefore it is not possible to win Turkey without winning in Istanbul. Or, those who lose Istanbul in the end will lose the country. This rule has never been negated.
