Well said, burzum! And your advice, "Lets not be tunnel sighted and only focus on the last type of attack. We need to be prepared for the next type of attack: think boxing.", is perfect!
Last word on this for me. I think we should really pull a surprise on them and completely get rid of the border, just remove it. See, that way they will think something really bad will happen to them once they step over what used to be a line. Kind of the old "train an elephant to not pull out a stake peg" trick. Plus; who wants to try and cross a border that isn't there? The challenge will be gone! well, gotta run, my tacos are burning!
