Justice for who?

While I strongly believe that the likes of Charles Taylor should be brought to justice for their crimes, however the United Nations and the international community seems to be applying the law very arbitrarily.
 
Are we ever going to see George Bush, Tony Blair, Paul Wolfowitz, Dick Cheney, Condoleezza Rice and other architects of the illegal oil war on Iraq, that, according to reputable estimates, has killed more than a hundred thousand Iraqis, also brought to book?
 
Furthermore, will the Israeli war criminals, such as Ariel Sharon, ever be brought  to justice for their crimes against defenceless Palestinians?
