George W. Bush has been tried and found guilty of genocide, crimes against peace, and crimes against humanity, by an International War Crimes Tribunal - the Kuala Lumpur War Crimes Commission, in compliance with proper legal process, on November 2, 2011.
The essence of legality is the principled, predictable, and consistent application of a single standard for the strong and the weak alike. Selective manipulation of international law by powerful states undermines its legitimacy.
The 2003 invasion of Iraq was an unlawful act of aggression and an international crime. It cannot be justified under any reasonable interpretation of international law. It violates the outer limits of laws regulating the use of force. It amounts to mass murder.
Unlawful use of force in Iraq threatens to return us to a world in which the law of the jungle prevails over the rule of law, with potentially disastrous consequences for the human rights not only of the Iraqis but of people throughout the region and the world.
The future of the United Nations and of the international law of war is also at stake. The unauthorized military action in Iraq undermines the system of collective security embedded in the United Nations Charter in order to protect humanity from a recurrence of the carnage of World War II.
The two [ George W. Bush/Tony Blair ] accused took the law into their own hands. They acted with deceit and with falsehood. They acted in flagrant violation of international law of war and peace. In the absence of any convincing evidence, defense assertions lack credibility. They appear to be fig leaves for hiding naked economic and political ambitions.
We therefore find that the charge against the two accused is proved beyond reasonable doubt. The two accused are, therefore, found guilty as charged and the two accused are accordingly convicted on the charge"..
In view of this verdict, the United States, where "no one is above the law", like you say President Barack Obama, is duty bound to bring George W. Bush to justice, by charging, indicting, and prosecuting him for these dastardly crimes he has been tried for, and found guilty of, by an international tribunal.
Commence the above action, as you are charged to do - your duty beckons.
