"The Pendulum of Turkey," this is how Savvas Kalenteridis named the policy that Turkey has been following since 2015 towards Russia and the USA, within the framework of Ankara's efforts on one hand to persuade Washington to abandon the Kurds and change its policy in Northern Syria, and on the other hand to secure its own vital space through oscillations between Moscow and Washington, to henceforth exercise its neo-Ottoman regional power policy. This entire process is described with articles and analyses included in the book "The Pendulum of Turkey," published by Infognomon, giving readers the opportunity to better follow developments in the issue of Ankara-Moscow-Washington relations, which is the most important issue that will determine the balances in the wider region.
