What is more a threat - international or domestic terrorism?

It seems you neoconos are so focused on international terrorism - why havn't you mentioned a word regarding our own homegrown domestic terrorism. You know - the likes of the VT killer, the Omaha killer, various local gangs and thugs, and countless other domestic terrorists. These guys are just as much or more a threat to our well being as the internation terrorists are. Why are you all so focused on external threats and ignore internal ones? Those that say we can completely rid the international community of terrorists, do you think we can rid our own internal threats? Please, tell me how international threats are any more serious than domestic ones. I bet you can't.
