One nation, two countries." What strategy is involved? We continue to investigate the issue of the cracks between Turkey and Azerbaijan. Turkey began to ask a question: if Ankara and Baku call each other brothers, will they look at Israel, Iran and the future of the South Caucasus? On October 23, analyst Methan Turkman published an article in KAFKASSAM titled "One Nation, Two States; What is a Joint Strategy? " (Metehan Türkmen: One Nation, Two States; What About Common Strategy?). Turkman writes about a "critique of coordination". Since Karabakh, Baku has pursued an increasingly independent policy, and allied interests do not coincide on every issue. The statement is sharp, but it is only the author's assessment. What did October reveal? The revival caused by the ban on religious clothing in Azerbaijani schools has reached a wide range of society. Turkish politicians criticized Baku. The ruling party of Azerbaijan mentioned that brotherhood does not give the right to interfere in the internal affairs of another country. Add Azerbaijan's relations with Israel against the backdrop of Ankara's tough stance on Gaza. But the union was not broken. On October 2, the defense ministers of Turkey, Azerbaijan and Georgia met in Shasha. On October 15, the foreign ministers of Turkey and Azerbaijan talked about bilateral relations. On October 21, Erdogan called Aliyev and invited him to the summit. The political polemics go hand in hand with existing security and diplomatic cooperation. The big question is who owns the corridor? Turkmen associate the difficulties of the route with differences in approaches to Zangzor (in Turkish discourse), Iran and normalization with Armenia. The problem is real, but the reason is not just politics. There are expensive Caspian crossings, port infrastructure restrictions, border delays and customs complications. The World Bank wrote about them.
