Nato entered uncharted territory on Tuesday when one of its members, Turkey, shot down a Russian warplane. There is an urgent need for Washington to bring both sides together to avoid World War Three.
Details are still emerging to corroborate Ankara's insistence that the jet had been repeatedly warned and violated Turkish airspace near its border with Syria. What is clear is that this incident has been a long-time in the making given the precipitous build-up between Ankara and Moscow over conflicting Syria policies. Since Russia started flying its warplanes over Syria in support of Assad, it has repeatedly violated Turkish airspace.
