Putin sends S-400 missiles to Syria to deter Turkey

In a move raising the potential threat of a Russia-NATO conflict, Russia said on Wednesday it will deploy long-range air defense missiles to its base in Syria and destroy any target that may threaten its warplanes following the downing of a Russian military jet by Turkey.

Although Russia’s state-owned RIA Novosti news agency has reported that Russia has already deployed long-range air defense missiles at its base in Syria.

The incident was the first time in half a century that a NATO member shot down a Russian plane. If Russia responds by downing a Turkish plane, NATO member Turkey could proclaim itself under attack and ask the alliance for military assistance.
