Militarize those borders!

I don't understand what people have against militarizing our borders. After all, our borders are enormous, and the easiest way to get nefarious characters into the country is through the miles and miles of nothing that line our borders - and Canada and Mexico aren't afraid of terrorists. Bringing our military home and stationing them all along our borders is a great idea, both because it will eliminate the source of propaganda for recruiting new terrorists and protect those already trained from coming across, at least to some extent.

Of course, this only works if an immigration policy which lets anyone who wants to come across to work come across is in place, and we dismantle the welfare state so that no freeriders will be interested. Otherwise things are just silly.
