Turkish President Recep Tayyip Erdoğan does not understand that his biggest divergence with Russia is over the future of all of Syria, not just a Syrian province. In theory, it is understandable that he wants to protect the “moderate fighters” because he feels indebted to them for their help to the Turkish army in two cross-border operations. But more than that, he wants to protect them in order to maintain a force that can eventually fight either or both of his two nemeses in Syria: President Assad and the Syrian Kurds.
