Thank you for being so arrogant as to "help me out".
What has America gained? Well - what it 'gained', and what it attempted to gain may have some discrepancies because of the abysmally executed (no pun intended) occupation, and ensuing insurgency/civil war.
Iraq has the fifth largest proven crude oil reserves in the world, and it passed Iran as the second largest producer of crude oil in OPEC at the end of 2012.

(Do I need to remind you of the great number of high ranking members of the Bush administration from the oil industry? G.W.Bush, Cheney, Rice...to name but a few)
Now, Cheney himself commissioned the Baker Institute Report:
STRATEGIC ENERGY POLICY: CHALLENGES FOR THE 21ST CENTURY in 2001, highlighting the 'threat' to 'American prosperity' posed by "scarce spare capacity" of resources and "Middle Eastern tensions" (ie Middle Eastern governments have control over their countries' oil supplies, which is a 'threat' to American industry and that is unacceptable to "US interests" [specifically that of the corporate vested interests of the Bush regime]);
"Iraq remains a destabilising influence to... the flow of oil to international markets from the Middle East. Saddam Hussein has also demonstrated a willingness to threaten to use the oil weapon and to use his own export programme to manipulate oil markets. This would display his personal power, enhance his image as a pan-Arab leader... and pressure others for a lifting of economic sanctions against his regime. The United States should conduct an immediate policy review toward Iraq including military, energy, economic and political/diplomatic assessments. The United States should then develop an integrated strategy with key allies in Europe and Asia, and with key countries in the Middle East, to restate goals with respect to Iraqi policy and to restore a cohesive coalition of key allies."
This article makes some very good points in regard to the
motivations leading up to the invasion of Iraq, in terms of strategic control of fossil fuels, US military presence in the region;
Brigadier-General James Ellery CBE, the Foreign Office's Senior Adviser to the Coalition Provisional Authority in Baghdad since 2003, had confirmed the critical role of Iraqi oil reserves in alleviating a "world shortage" of conventional oil. The Iraq War has helped to head off what Ellery described as "the tide of Easternisation" – a shift in global political and economic power toward China and India, to whom goes "two thirds of the Middle East's oil."
So, in other words - the US sought to fend of other contenders for global power (call it what you will) - by asserting "Superpower" dominance, using a series of allegations of Iraq's weapons program and links to militant Islamists (both of which are demonstrably false).
Now, besides the strategic, political and corporate muscle flexing that went on there, the US government called upon some of its more...loyal allies to take part in this shady exercise in plunder.
Australia and Britain, for example went into battle - not for any "moral imperative" as their political and bureaucratic spin doctors tried to sell their populations at the time - but because he US was leaning very heavily on them for support.
Australia, for example, took part in the invasion
without our Federal Parliament being consulted.
This was a deeply unpopular course of action for the Government to take, sending our military off to a war under extremely dubious pretences - but our government did so anyway.
Why?
Because of the threat - used time and time again by US governments and the State Department - to withdraw US support (military, trade and other geopolitical benefits of being cosy with Uncle Sam) - if we did not participate.
Now - Australia is
not a Republic - we are still, in formal terms - a British Colony.
But as you most likely are aware, the British Empire became more or less a ceremonial formality (and nothing more) in the years since the Second World War.
Britain - in a military and global political sense - is part of a bigger Imperial force; that of the United States. Or NATO, as the broader alliance is called - but it is evident who is the power broker in that relationship.
So, Australian service men and women were pulled along with the UK, who in turn were left with little option but to pursue this war, as "the Coalition of the Willing" - an ironic term if ever there was one.
The relevance of this, in answering your question?
Not only were efforts made to secure Middle Eastern resource interests, but the US govt also made an Imperialist play at ensuring support from her privately sceptical - yet publicly enthusiastic allies.
There are many examples of the US replacing Britain as Australia's Imperial overseer and big brother (quite literally - as much of the satellite surveillance technology infrastructure used in the Iraq Invasion - and subsequent extrajudicial drone killings in more recent times - has been centred out of a top secret CIA communications base in the Australian outback called Pine Gap. The Australian public are not privy to
any information about what the base is used for, except for odd congratulatory remark from US sources when another carload of people gets blown to smithereens in Yemen or some such place).
The Australian government has limited autonomy - anything the federal government wishes to pursue, policy-wise (from enquiries into the Pine Gap facility [in the early 1970s] to a trial of medically prescribed heroin maintenance [in the late 1990s, I believe] has been shut down due to pressure - or worse, from our US "allies").
Modern day imperialism isn't about conquering the natives and proclaiming "this land belongs to the American empire" - it is far more complex than that.
The Invasion of Iraq not only attempted to secure US oil supplies; but also a military support team for their otherwise "unilateral" actions.
The first objective, I cannot say I've investigated too deeply (in terms of its "success" or otherwise) - but the latter exercise in international coercion in following American agenda, in the case of my country and the UK (in the face of widespread public opposition in those countries) was a complete success.
And there you have it - Modern day Imperialism.
Not for "King and country" but for "Control and corporate dominance".
