Whoever made that post on Reddit was unwise, but he was not incorrect. I'm also of the belief that if there truly were a very large organized effort to terrorize the US there would have been at least 10x more events that have occurred. Therefore, while there may be an effort, it seems to be a fairly small or pathetically weak one, in relative terms. Can't believe the hundreds of billions they're spending in the name of fighting it. Though at least UAV/robotics is getting lots of funding and advancing steadily -- the one bright spot in the CS industry that has been positively impacted by it all.
