George W. Bush et al real reasons for going to war with Iraq.
I will repeat and expand what I've said before (in a not very scholarly organized manner, I'm afraid. I wish I was as good at this as our Setanta.)
I've come to believe that the real reason Bush et al was determined to invade Iraq is not very complicated, but the real reason was politically incorrect, making it impossible to be truthful with the American people and the world.
When we invaded Iraq the first time to liberate Kuwait, Saudi Arabia's royal family allowed US troops to enter the Kingdom to pursue the war led by Bush senior. This inflamed Osama bin Laden and other Muslims in Saudi Arabia and throughout the Arab world. The war was won and Kuwait was liberated. Some US troops in Saudi Arabia were sent home, but many remained on "temporary" bases that the US built.
Later, as bin Laden began his campaign to overthrow the Saudi royal family with strong support from the non-royal population, the Saudi royals put pressure on George W. Bush to remove all US troops from the Kingdom, Bush had to find another place to relocate our troops and to build bases. Why? There was fear that the pro-west faction of the Saudi royal family might not prevail. Bush had to act to ease the pressure on them. Why? To prevent Saudi oil from falling into bin Laden's hands if he was successful in overthrowing the Saudi royals who did not support his ideology.
Other than Kuwait, which had allowed limited US presence in their land (it would have been hard to refuse the US after being liberated) there were few countries in the region that would tolerate a US troop presence. Iraq was a sitting duck when Bush was looking for a country in which to build bases to protect US and other Western oil interests. We were already controlling large areas of Iraq. Iraqi president Saddam Hussein et al was a very bad man and the world would cheer his elimination.
Bush et al had to mask his real purpose and created several versions of why we should invade Iraq: WMDs, terrorism, liberation of the Iraqi people, spreading democracy, etc. None of which had anything to do with Bush et al goals. To get US bases in the regions to protect access and control of oil. That was something the British could also support given their long history of such actions.
The US is now completing fourteen bases in Iraq with a little time and money left over to restore Iraq. Do you really believe the US will abandon these bases after the Iraqi government has taken pseudo control of their country? Don't hold your breath. The US has a pattern of remaining on their bases around the world for a long, long time.
Several goals were achieved by Bush plans. It got US troops out of Saudi Arabia and bought the pro-west branch of the royal family time to fight their internal terrorists to save their control, and to take baby steps toward reform that would benefit their citizens.
It allowed fourteen bases in Iraq as a barrier to aggression by Iran in support of the Iraqi Shiite population. It preserved western control of Iraq's oil in the face of increasing Irani militancy. Without Bush's action, both Saudi and Iraq oil access was threatened.
It allowed semi-independence by Iraqi Kurds, which eased the tension with Turkey. Turkey, a country trying to modernize, wanted to join the EU and Kurd conflict would have made their goal difficult if not impossible.
Unfortunately, Bush's short-term goals to protect US and western oil interests have sewn the seeds of long-term conflict with great risk to the US. The conflict has only begun. In the meantime, Bush et al has done nothing to reduce US dependence on foreign oil. That doesn't only mean Middle East oil, but oil-rich countries in other parts of the world. South America and Asia comes to mind.
Sorry this is so rambling, I hope it makes sense.
I just found a site that seems to have the same conclusion as mine. which I haven't read yet, but it is much better documented and written:
