Actually yeah it doesn't because look at this simple fact. It is easy to be a terrorist and if they truly wanted to do us harm they could have. I mean like I said before were a big country with a huge open border.
Except they tried and failed, repeatedly, which the link I posted shows.
They're not really going to walk into liquor store and shoot a clerk. They try and plan attacks on a much broader scale. They want a much bigger impact.
I agree we are extremely vulnerable. Another major attack is coming. We have done a phenomenal job since 9/11, but we will not be able to stop every attack planned by those cockroaches.
