Everyone anti-war was expecting this a government white wash but tbh, it was quite critical of Tony Blair and his decision making process on going to war but the Inquiry couldn't say it was illegal as it wasn't set out to find out whether it was or not.
Blair overestimated the threat of Saddam it said, by using flawed intelligence; declassified documents showed Blair sent a memo to Bush eight months prior to war saying he'd be with him, whatever; no planning on post-war; no influence in post-war and all the accusations against Blair seem to be levied at him.
He, of course believes it was the right decision. That stance probably motivated by impending lawsuits if he was to say it was the wrong decision I'd imagine (nothing that income raking he generates for dictators wouldn't cover) but the media - especially those newspapers who were pro-war and were horribly brutal and vindictive to those anti-war - need to own up and apologise. But that won't happen.
Robin Cook, rightly remembered for his resignation prior to the war and said in a short speech what it has taken 7 years, 2.6m words, and to a cost of £10m for the Iraq Inquiry.
Cameron blathering on about lessons being learned yet his own military escapade in Libya has proven to be a great 'success'...
Iraq War was Blair's worst decision period and luckily for him, it's others (hundreds of thousands of Iraqis who died, British army personnel) who have and will suffer.
