Of course there are different ways of making sense of the evidence and the facts before us, and people can disagree about what needs to be done and all that - but that is different from a situation where large numbers of people are persuaded to believe things that patently are not true, by people who know they are not true, as a way of achieving political power.

The leaders of the administration in America know perfectly well that Iraq had no Weapons of Mass Destruction, even if perhaps at the time of the invasion they might have believed it did, and they know that Saddam had nothing to do with Al Qaeda or with 9/11. But they have done nothing to disabuse their followers about these falsehoods, and in fact they have done the reverse.

There aren't two realities here.There is one reality and a series of lies being exploited by people who know they are lies.
