I think that any solution must come from the answer to that question. It seems to me that terrorism is hard wired into our DNA. Please ask yourself whether you would ever join a terror group that is planning to kill millions of people. Then please consider what you would do in the following scenario. Radical Muslims develop a virus that kills 99% of all Americans. Your loved ones all die and you are one of a few million survivors. The Radical Muslims then take control of the United States and enslave almost all of the survivors, raping the women and castrating the men. You manage to hook up with a resistance cell, and they have a plan to release a virus that will cause most of the Muslims to die horrible deaths. You can help in this effort, knowing that you will be killed during the mission. Would you participate? When I think about this scenario my sense is that I have an innate impulse to get revenge and my heartbeat increases and I feel good about dead Muslims. I see two ways to go here. We can ask France to join us and twenty or thirty other countries in sending 5,000 troops apiece to wipe ISIS from the map. Countries that come immediately to mind include England, Canada, Australia, New Zealand, Germany, Russia, Ukraine, China, Egypt, Saudi Arabia, Jordan, Kuwait, Iran, Pakistan, India, and Turkey. With enough allies, this should be a piece of cake, and ideally this would promote good feelings among countries who have bad relationships, such as Russia and the Ukraine. History shows that nothing brings countries together as quickly as a common enemy. One very bad thing about this plan is lots of people would die, including innocent women and children. Another bad thing is that it would likely result in more terrorism. These killers in Paris were not cowards -- they knew that they would die. If we wipe out ISIS, it seems inevitable that their brethren will seek revenge. That leads to the other way to go, which is the path of peace. I think that such path requires dropping any pretense that the Western powers are innocent in all of this. Let's face it. The record of the Western powers in the middle east has been abysmal. To name a few of many examples, we put the Shah in power, we sold chemical weapons to Saddam that he used to kill a lot of people, and we are the main prop for the disgusting Saudi regime. More recently, the war to remove Saddam cost hundreds of thousands of Iraqi lives. It seems obvious why are we hated. It's human nature for people to want revenge when their countries are invaded and occupied and their loved ones are wounded/killed and they see pictures of their countrymen being tortured in a prison like Abu Grabe? Summing this up, if I were an Iraqi and my family was wiped out by a stray American drone, my first thought would be how can I kill as many Americans as possible. And it would take a lot to restrain that primal impulse. However, it seems indisputable that violence begets violence. Consider Rome versus Carthage, England versus France and the Crusades -- humans are capable of carrying on wars for decades and sometimes centuries. Each group sees itself as the good people and their enemies as the bad people. How do we break this cycle? Peace is hard. It requires admitting past mistakes. It also requires compromise and accommodation. My experience in making peace is that it is critical to address the core interests of each side. In this case, ISIS wants its own country -- a caliphate that would be a theocracy. I think that we should put this on the bargaining table. Frankly, I like the idea of having as many of these radical Muslims in one place as possible and I can live with the fact that they will oppress their own people (who choose not to get out while the getting is good). Thus, I would let them have their caliphate, subject to an agreement of all civilized countries not to sell them any weapons or technology. Let them live in the 7th century and leave them alone as much as possible.
