In an unfortunate coincidence (or convenient bit of political timing) last night, on the eve of 9/11, President Obama addressed the world regarding the looming threat of ISIS and laid out America's plan to arm Syrian rebels and engage and destroy this group of extremists. It's too open and shut. ISIS is bad. Something must be done. We are going to do something about it. Not a word of how we got here. Not a moment to contemplate how the next step might create the next open and shut situation. Many regretful events led to the horror of September 11th and many more continue to happen as a consequence of it. To ignore this and go forward without learning a lesson from the price those people paid is a shame.
