“…the events unfolding in Iraq point toward a much wider war, reaching from the Iranian frontier to the Mediterranean coast. The long open border between Iraq and Syria, and the big stretches of ungoverned space, has allowed extremists on each side to grow and to support one another. isis and Jabhat al-Nusra, two of the strongest groups fighting in Syria, were created by militant leaders from Iraq, many of whom had fought with Al Qaeda in Mesopotamia against the United States. The vast swath of territory between the Euphrates and the Tigris—from Aleppo, in Syria, to Mosul, in Iraq—threatens to become a sanctuary for the most virulent Islamist pathologies, not unlike what flourished in Afghanistan in the years before 9/11. Among those fighting with isis and Al Nusra are hundreds of Westerners, from Germany, the United Kingdom, France, and the United States. At some point, the survivors will want to go home; they will be well trained and battle-hardened. The extremist groups dominating the fighting are beginning to take their war beyond the two countries that they now freely traverse. In January, isis carried out a car-bomb attack in Beirut near the offices of Hezbollah, the Lebanese militant group that has been fighting on behalf of Assad. The Nusra front has also carried out attacks in Lebanon. Meanwhile, the number of Syrian refugees who have fled to that nation exceeds twenty per cent of its population, which is not something that a state as weak and as fractious as Lebanon can be expected to sustain. In Jordan, the presence of half a million Syrian refugees is putting an enormous strain on the fragile monarchy.”
