Pretty much spot on with my thoughts; defence of the Homeland just has to be the No 1 priority - who would have predicted 9/11? WRT "what's the realistic threat"; with the benefit of several years experience since 9/11one would like to think that the warnings and indicators would now be in place to give us the "heads up" and posture accordingly and, from experience, I do think there is a threat, albeit relatively small - but that's all it takes if you are not prepared. However, that does not detract from CM's opinion.
