You can't possibly be serious. I'll give you a hint: When something is hidden, it is not generally known where it is.
Since when does, "How dare you criticize the criticizer!" - qualify as democracy or free speech? Your point reflects a typical anti-patriotic, anti-nationalism, globalistic cynicism which is the hallmark of 60s liberalism.
If your criticism is why haven't we, in 10 weeks, uncovered more of the unaccounted for WMD than two buried biological weapons labs, fine. I don't know, but I haven't run out of patience yet.
If your point is why, after 10 years of intelligence reporting by the US, Canada, UK, Germany, Isreal, etc. and inspections by the UN - all describing (and finding pieces of) Iraqi WMD programs - some partisan ideologues would so obviously run against history to attack Bush/Blair, it's simply because they believe you and others will not hold them responsible for being liars and reprobates.
Perhaps that is what you mean by an intelligent discussion in the UK?
