Somehow I think downing a non NATO aircraft in non NATO airspace involving a non NATO action invokes article “don’t be stupid” not article V.
Russia will not attack Turkey any more than we attacked the Soviet Union after they shot down more than a dozen US military aircraft during the Cold War. This will all blow over. And the Russians will be very careful about being near Turkish air space. The Russians were warned by the Turks two successive days before the shoot down that they would not tolerate continued Russian violation of their airspace. The Russian ambassador was called in twice.
