On November 12, the day before the attack on Paris, ISIS committed a horrific terrorist attack on innocent citizens of Beirut. Like the Paris attack, it was coordinated and commanded by ISIS. Like the Paris attack, it was executed by a cell of terrorist suicide bombers. Like in Paris, a manhunt ensued to find a network of planners and associates behind the bombers, and the Lebanese authorities have arrested nine people for suspected involvement in the attack. The two tragedies, one in Paris and the other in the largely French-speaking city once known as the “Paris of the Middle East,” were remarkably similar. The most significant difference between the two attacks was the relative severity; the Beirut attack was far worse than the attack on Paris. Were the same proportion of the French population killed as in the Lebanon attack, Paris would have suffered 635 deaths. In fact, the attack exceeded the deadliness of 9/11 in terms of the proportion of citizens killed. The same magnitude of attack would have claimed almost 3,100 New Yorkers’ lives.
