UK Elections -did Blair lie to go to war ?

In my mind this one is simple- but has not been addressed.
The public were told that Iraq had WMD and that was threatening UK citizens.
They weren't but were only threatening UK tourists in Malta and a couple of soldiers there.
QED
Sorry about spouting this for the second time, but it does seem a tad obvious.
Being blunt Blair is guilty of murder.
Arguments about it was good to get rid of Saddam are irrelevant, which Blair is spouting . As we have seen from this adventure, it is possible to get the populace of a country accepting [ well only just in this instance- most of the country knew it was wrong ] by using propaganda techniques.
It isn't a huge step for a country that might go to war for huge humanitarian reasons - say another country it didn't like - that had abortion on demand -- wow a country that kills its own infants - gotta be right to stop that...
or allowing gay marriages- going against god's will - another must do..
The above 'might' sound utter tripe, but who knows what moralisings might spring up in the future- invading a sovereign state for whatever reason[ ie Bush wanted to finish what his dad started ] can have horrible future repercussions- and I worry about it.
A final note - those inspectors who weren't allowed to veiw areas that probably had WMD, notably the presidential palaces - Would a dictator or anyone else in power for that reason have bugs/nukes/chemicals (other than Domestos) inside/under/near their house ? I think not . Yet this was part of the pre-pretext for invasion
