Turkey’s planned purchase of the S-400 missile defense system from Russia threatens NATO security and is putting Ankara at risk of losing its status of “a critical partner in the most successful military alliance in history,” US Vice President Mike Pence has warned. Experts from the Turkish Foundation for Political, Economic and Social Research (SETA) participating in a panel discussion, organized by the Valdai Discussion Club in Moscow, spoke about the problems currently existing between Turkey and the United States as well as their country’s cooperation with Russia.

Ukraine’s recent provocation in the Black Sea has become another pretext for unraveling the Yalta system of international institutions and legal accords, which has been actively and openly done since 2014. Before that, it was Yugoslavia, Iraq, Libya, a bungled attempt to do the same in Syria, as well as a series of "color revolutions," orchestrated in close vicinity of the Russian borders, including the so-called “Revolution of Dignity” in Ukraine.
