Hypocricy on Trial

If the killing of 148 people now counts as a crime against humanity and you can be cynically executed for it on the eve of one of your religion's holy days as has just happend with Saddam Hussain, what then should be the punishment for the commission of aggressive war that constitutes "a serious attack on human dignity or grave humiliation or a degradation of one or more human beings. They are not isolated or sporadic events, but are part either of a government policy (although the perpetrators need not identify themselves with this policy) or of a wide practice of atrocities tolerated or condoned by a government or a de facto authority"?
I refer of course to the systematic destruction of the Iraqi infrastructure in the days preceeding the invasion and occupation of Iraq. How many civilians died a part of the "collateral damage"Mister Blair as part of your government's policy? Will you be put on trial and then hung on Christmas eve or the early hours of Good Friday? Didn't think so, but then the rules are always written by those with the greater might aren't they?
