Terrorism for a cause?

I stumbled upon this clip back on Metacafe. like all normal civilised person I felt disgusted by the attack on defenceless civilians. All the perpetrators and their accomplices should be tracked down and punished. But then again, why this this happen in the first place. While the west pays no attention to similar or even worse events on a much grander scale in Chechnya, nobody could ignore this one. The loss of life is sad but the fact that it is the only option left for the combatants is even worse. This is no way to fight for one's freedom, this is an act of desperation. What would you do if you were a Chechen who cares about his or her country?
