Had the Bush administration handed over Saddam Hussein to the International Criminal Court to be dealt with, or whatever other International court would have had such appropriate jurisdiction in such matters, Saddam would have spent the rest of his life in prison for not only crimes against humanity but also for a whole range of other crimes including various war crimes that he undoubtedly would have been found guilty of.
However, in allowing this to have happened Bush would have opened if not himself then most certainly other officials of both this and previous administrations to having been complicit to some extent or another in many of Saddams other crimes. Indeed, the crime that Saddam was actually tried and executed for was deliberately and carefully chosen because it was one of the very, very few of Saddams crimes that the US was not actually complicit or implicated in thus ensuring that their other secrets are now safe.
With Saddams death comes a collective sigh of relief from those around Bush that may have been implicated by a full international trial of Saddam where all of his skeletons would have fallen out of the closet exposing the whole rotten mess that is US complicity in Middle East ratbaggery. But that collective sigh of relief could still turn into a gasp of horror as Bush and his cronies realise that, by setting the precedent of allowing Saddam to be executed in a country that does have the death penalty for such crimes, that they too could well find themselves facing the people of their own nation to answer similar crimes.
There would be a certain irony in the fact that the very laws the present US criminals created to ‘protect’ American citizens from the International Criminal Court, which doesn’t have a death penalty, meant that they had to face those charges in the US which does have a death penalty.
