"Ok, so I'm a terrorist, but what would you call them (the Russians)?"Let's review.
Do the Russians make it their Modus Operandi to kidnap civillians and threaten to, and indeed, kill them if their demands aren't met? Do they attack civilians in order to strike fear into other civilians to affect policy?
Conclusion: the Russians are not terrorists.
You can be wrong and not be a terrorist (not saying the Russians are right or wrong here, just leaving that judgement open). You can even kill civilians and not be a terrorist. Terrorists mean to kill civilians, and the more the better.
As long as people buy the moral equivalence argument that a death = a death, we, the civilized people of the world, will never win "The War on Terror".
Party A being wrong does not justify terrorism on the part of Party B. Nothing does.
Terrorism is always wrong, even if your cause is just.
