Your position is that if we cannot have perfect justice why even try for justice at all.
No. My position is that if you can’t get people to agree on what justice is, then trying to enforce one person’s definition of it is rather futile.
I think we can agree that the use of WMD is a war crime. As soon as you move from that standard and try to set another bar down lower, you start to lose that agreement.
Ask a Serb if Milosevic is a war criminal or a hero.
