Americans have been safe for so long that we all have a false sence of secutity. The terrorist threat is real and present, it is no longer a matter of "If", today it is "When."
With our immigration practices, I am sure we currently have thousands of terrorist on American soil. They are biding their time, waiting for instruction and/or an opportunity to do damage. What concerns me is how many have slipped through the cracks while our elected officials have their backs turned, and how many more will join them before we tighten up our border controls?
