Was Ambassador Christopher Stevens running guns to Syria for the CIA when he was killed in September 2012 in Benghazi? New evidence points in that direction. The United States has been repeatedly accused of arming Syrian Islamists, in part with Libyan weapons shipped through Nato to Turkey and then over the border. An interview in Aleppo by a German reporter (1), released this week and given wide coverage in Germany and Russia but little elsewhere , brings further proof to the allegations. But US complicity with the Islamists goes much deeper.
