In 1946, many of the German High command both civil and military, were executed for various offences, mainly, Crimes against Humanity and Waging Aggressive War.
What has happened in the recent past in my view could be considered these crimes. Blair has misled Parliament and the people of the UK into waging wars which have still not ended, both in Iraq and Afghanistan, committing British forces into a conflict without end. Some people of a left ward political leaning claim the Conservative Party also approved of the invasion of Iraq, yes this is true but they will have received briefings under Privy Council rules and what were they told or misled into believing is the most important part.
The Chillcot enquirey maybe muzzled due to the civil servants stopping evidence about the conversations between Blair and Bush being revealed.
One day I hope he and others involved will be arrested and tried as a war criminals at the Hague and receive a due sentence.
