Your comment can be applied to virtually every war in human history. Actually no one at any time understands all of the (even major) consequences of any significant conflict, civil or military. You could make up an interesting parlor game as to any major event, having your guests compete as to whom can identify the most unintended &/or unstated consequences.
So can we finally stop saying that one comment in one letter written towards the beginning of the war gives the one and only one reason for the fighting and the whole meaning of the conflict?
