drjarhead,
I think at some point someone will draw that line in the sand and when they do God help them because if they are successful they will be the next Osama Ben Laden. But, I think they might have a bigger following then any Al-Q wonnabes... provided he/they live long enough to "enjoy" the fame.
The thing to remember is that we are the what the criminals in office fear. As for foreign troops, other then Canada and Mexican troops, we have SA commies and such who can be here. With Obama in office he will be more then happy to get UN troops involved. He will open our borders to foriegn troops...
