with your assessment
it doesn't sound like Al Queda to me
they didn't do the martyr thing
and ETA has been becoming more radical
and has probably learned a thing or two from the muslim terrorists, now they are going for body count
I can only imagine the oppression one must feel in order to resort to terrorism but it seems to me that you wouldn't go to those extremes without a pretty legitimate grievance. The Basques want independance. If the American Revolution were happening today, the British would call George Washington a terrorist.
The best defence against terrorism is to resolve the issues that cause people to feel disempowered to the point of desperation
