Really now that actually taking control of a commercial aircraft is all but impossible, those aircraft are no longer the really high value targets.
It's not so much that it is a high value target anymore. Hell these people really aren't after high value targets, if they can get one in the process that is gravy, but otherwise they are only in it to sew the seeds of fear. Their only discernible goal is to cause as many people as possible to be inconvenienced or waste as much money as possible. The whole goal is to degrade the value of western society as we know it. The fact that the US and the world for that matter has reacted they way it has means they have been successful. The leaders have even publicly stated they consider these "failures" to be successes because people are scared and more money is being wasted on "security measures".
It may sound callous but I think that the only way to defeat these idiots is to not change anything and to just go about our lives. Yeah they blew up a plane and a lot of people died. OK we mourn the dead, get over it, and move on. No costly changes to procedure no fear of what will be next. Eventually services to the areas they infect will diminish, i.e. no air travel or cargo in or out, etc. They can go back to living in the stone age and the locals will suffer and eventually rise up and better themselves or continue to live blissful and ignorant.
I do believe in equality for ALL people all over the world and I work towards a peaceful secular society in my actions daily but until that happens what else do we have but life, liberty, and happiness?
