Just to toss out my personal opinion (which I hope doesn't backfire into an argument), all persons participating in terrorist activities, or members proven to be of terrorist factions (whether or not they've gotten around to killing someone yet) should be stripped of all moral human rights and excecuted.
Yes, it's a voilent solution.
Yes, it sounds like a witch hunt.
But last I heard, they don't have a "Diplomacy 101" course in terrorist training facilities. They're trained to kill, plain and simple, and take their own lives as well if it adds a few more innocent casualties. They're taught two things: Mass Murder and Chaos. Those are two things that cannot be stopped by any type of peacefull means.
As far as cease-fires or shit like that, I would never make such a proposal to a terrorist faction, nor would I so much as listen to one from them. Honor is something terrorists do NOT posess.
I don't consider myself a really violent person, I have no desire to harm others over political, religious, (etc.) reasons, but if by some small chance I happened to cross the path of a terrorist someday, whether engaging in a terrorist activity at the time or not, I'd happily execute them with a big fuckin smile on my face.
On a side note (I can't believe I'm going into a lengthy poilitical post...), without naming names, FUCK any of the countries who have refused to take action against terrorism without valid cause. It will hit your country too someday, extremists will always be around, it's just a matter of time. And when that day comes, call up President BasilisK and ask for foreign aid. I'm looking forward to reminding you of the day your "allies" needed your help and you stuck your noses in the air, then telling you to go fuck your mother, deal with it yourself.
mmmmmkay I'm done ranting now
