@SwamP-ThinG - by "you" do you mean me or do you mean "the US"? I only ask because, although it's quite clear that I haven't offered up any solutions (save agreeing with Startup), your post seems to imply that I have.

And if I read you right, your solution is to prevent terrorists from entering your country. I would have to agree that this is a valid solution as well. Still, I can't help wondering about what a monumental endeavor this would be given the volume of trade into and out of this country. Additionally, seems the US has been much maligned in the past for attempting to control our borders. Also, we don't seem to do a very good job of it.

But, over-riding all of these concerns is that I have a problem with any country having to be concerned about its civilians being targets of heavy military ordnance. Shouldn't all civilized nations take whatever steps are necessary to eradicate this problem and condemn it with action rather than words? And, if so, what are the limits of these actions, if any?
