"John Bolton was not an elected politician - his most senior position was 18 months (or so) as UN ambassador. What did he do there that was illegal ?".Good question, because even if you accept that the invasion of Iraq was a war crime perpetrated by Chimp-McHitlerburton in order to steal oil then it is still hard to see what crime John Bolton has committed, he did not plan ot execute the invasion. All the specific examples of Bolton's perfidy that Monbiot gives come down to John Bolton having different opinions to George Monbiot. For instance he cites Bolton's negotiation of the end of an arms control treaty with Russia, the treaties themselves were never signed on the basis that the could never be repealed, but in the hands of the far left this is a violation of international law.
Laws are supposed to be an agreed set of rules and principles by which people can adjust their behaviour to stay legal, in the hands of the far left 'law' is a series of elephant traps by which political opponents can be ensnared and silenced for doing things that nobody was aware was illegal. These people seriously wonder why the United States doesn't sign up to the International Criminal Court.
