Leave them alone and they'll let you alone.
Terrorists in our countries? Yes, it could very well be the case.
That's a police matter, a secret service matter, interpol matter, special services matter, justice matter, criminal matter but not military matter.
It's inside your country that it matters, NOT halfway around the globe in a country with no WMDs, no connection, prior to the war, with those who committed 9/11.
