I believe that's the reasonning that takes place in many Algerian officials. They do that against Europen countries mostly. The question of terrorism is very complex, I realize. I have taken the outh to become a US citizen, and I couldn't bring my own mother to meet my fiancee, an anglo nicest woman on earth, because I might be a terrorist, or perhaps her at age 62, weak and hanging there only because she hasn't seen me for 15 years. You must be with the FBI, CIA, USIA, or some University, which ever it is, I hope your interest is in stopping it.
Life is so short to be wasted like that.
