He went to the UN as US Ambassador through the back door, when President Bush appointed him during a Congressional recess, meaning he was never approved, even by a Congress that was dominated by Republicans.
Today newspapers around the world screamed in absolute delight as one of the worst neocons packs up his bag to leave a post he was never meant to occupy. They say:
John Bolton, the controversial and outspoken US ambassador to the United Nations, will step down when his temporary appointment expires within weeks.
Bolton was unable to continue in office after George Bush's Republican party failed to take keep of the US congress in the recent elections.
Entered sneakily by the back door, now leave in similar ignominious manner. How sweet for those who waited for this day.
