We will not negotiate with terrorists

[Soulforged]

If you accede to their demands at all, then it will encourage more terrorism.

I don't think so Divinus. Terrorism is occasioned by an original cause, that still exists (like for example looking for independence) and as long as this root exists you'll have terrorism. If you accede to their demands it will not exactly encourage terrorism it will only sustain the status quo. As I see it the only occasion in wich that logic might work out is when the terrorists in question only do terrorism for money, a la mercenary, or when they do it for simple pleasure wich is rather improbable.
I think that negotiation is unavoidable, both, before the terroist group is destroyed, and after (if destroyed). The expression "we will not negotiate with terrorists" might sound brave and attract the public attention, but it really is foolish and futile.
