The soviets did not kill over 3 thousand americans on our own soil. They also never destroyed any of our skyscrapers. Clearly, the muslim extremists are a proven greater threat. When they get a hold of a nuke, we will lose an entire city. Our borders are wide open and we are ripe for the picking. For proof ask any drug addict how easy it was to get hard drugs. The modern day muslim extremists are just like the ancient Huns. Playing the US Empire for fools, just like the Huns played the Romans. The outcome is far from certain and we need to deal with the Barbarians as they deal with us.
