That Bush speech was after the invasion. Before the invasion the discourse was centred in the Atomic Weapons, later changed to Massive Destruction Weapons (to include chemical), later to something else, since there was no WMD. The Casus Belli for Iraq was one of the biggest forgeries of the last 100 years. But now, since Iraq was invaded there is no need to maintain the forgery anymore. What is curious is that it was a lie repeated so many times that many people begun to believe in it. Anyway after the mess was done, currently the West, and not just the USA and the UK, needs to find a solution for the chaos that was installed after the invasion.I'm not so sure it was "bollocks."
C.I.A. Is Said to Have Bought and Destroyed Iraqi Chemical Weapons
As to the reason(s) for the US invasion, there were myriad reasons, goals, agendas and objectives that were touted at any given time.
"We have difficult work to do in Iraq. We are bringing order to parts of that country that remain dangerous. We are pursuing and finding leaders of the old regime, who will be held to account for their crimes. We have begun the search for hidden chemical and biological weapons, and already know of hundreds of sites that will be investigated. We are helping to rebuild Iraq, where the dictator built palaces for himself, instead of hospitals and schools. And we will stand with the new leaders of Iraq as they establish a government of, by, and for the Iraqi people. The transition from dictatorship to democracy will take time, but it is worth every effort. Our coalition will stay until our work is done. And then we will leave — and we will leave behind a free Iraq."

My point is that it is never absolutely clear as to why governments get involved/start conflicts, it's murky. The same goes for Afghanistan: initially, all the US wanted was to get Osmama, right? Well, they got him in 2011, yet, here we are, eight years later and we're still there.
