I would agree about the notion you can't make killing people a matter of morality. No one should ever be killed.
I think the only moral war is the one where another nation attacks you, and you have no choice but to defend yourself. That may be the only moral war.
Now, there are some just wars where you are defending your allies. I don't really buy too much into the 'We're doing this to help poor, impoverished people' - If that was the case, we would help out in the Rwandan conflict, East Timor, Darfur, Burma, ect. The truth is that there are lots of horrible, abysmal people out there doing some awful things. I think that one strategy the west can employ is that of social traffic - that is, if you don't like what *they* (the aggressors and abusers of human rights) don't like what is going on, then move to a nation that will treat you fairly. That way, you aren't involved in conflict, benefit by new population groups, and remove the threat from the aggressor.
Back from the dead, I'm afraid.
