True.. "ISIS/Al Qaeda/Dark-bearded-terrorist-du-jour" is probably inside the US already. Just the way it is. Of course, clamoring "barbarians at the gates" is always a nice way to prep for expanding Govt. power and cinching down on the Constitution.
I find it funny how we are repeating history:
1)Foreign Govt crosses US Govt.
2)US Govt funds and provides material support for "freedom fighters" to oppose said Foreign Govt's interests
3)Freedom Fighters start colliding with US interests too and are rebranded "Terrorists/trrrsts/extremists"
4)9/11
5)"we need to take your freedoms away so you'll be safe", "if you argue against, you hate 'Merica"
Currently on No. 3 with "ISIS"
