Here's an odd thing.

In discussing the war it seems almost everyone agrees that a soldier who commits a war crime is culpable.  If he knowingly shoots a civilian for example, even when ordered to by a superior, he commits a crime.  But almost nobody seems to think that a soldier should be held personally accountable for the worse crime known as a crime against the peace, by which I mean the particpation in a criminal war itself.  Why is this?
