French President Hollande has described the attack on Paris as an act of war. Those words have meaning. One gets the same feeling as after 9/11, when the American people rose up as one and said, “Enough!” But it’s not enough for a single country to react. A global coalition needs to band together to take on this self-declared Caliphate by any and all means. Destroying the Islamic State is not a cure-all. Self-actualized terrorists are here to stay. Rooting them out will take decades. But sometimes governments have to act in the moment. This is one of those times.
