The Iraq War, also known as the War in Iraq, the Occupation of Iraq, the Second Gulf War, Gulf War II, and Gulf War 2, was an armed conflict in Iraq that consisted of two phases. The first was an invasion of Iraq starting on 20 March 2003 by an invasion force led by the United States. It was followed by a longer phase of fighting, in which an insurgency emerged to oppose the occupying forces and the newly formed Iraqi government. Roughly 96.5 percent of the casualties suffered by the U.S.-led coalition were suffered during the second phase, rather than the initial invasion. The U.S. completed its withdrawal of military personnel in December 2011, during the ninth year of the war. However, the insurgency is ongoing and continues to cause thousands of fatalities. Throughout the armed conflict, the United States never formally declared war on Iraq, making the war a military action.
- I like to tell people when the final history is written on Iraq, it will look like just a comma because there is — my point is, there's a strong will for democracy.
- [T]here is no longer a preponderance of military force that allows the West to impose its will, the U.S. defeat in Iraq being the most extraordinary illustration of that fact.

- It's an intelligence document written by the then head of Iraqi intelligence, Habbush to Saddam. It's dated the 1st of July, 2001. And it‘s basically a memo saying that Mohammed Atta has successfully completed a training course at the house of Abu Nidal, the infamous Palestinian terrorist, who, of course, was killed by Saddam a couple of months later. Now, this is the first, really, concrete proof that al Qaeda was working with Saddam. It‘s a very explosive development

- As I have heard Bush say, only a wartime president is likely to achieve greatness, in part because the epochal upheavals of war provide the opportunity for transformative change of the kind Bush hoped to achieve. In Iraq, Bush saw his opportunity to create a legacy of greatness.

- In this case, the 'liberal media' didn't live up to its reputation. If it had, the country would have been better served.

- As a Texas loyalist who followed Bush to Washington with great hope and personal affection and as a proud member of his administration, I was all too ready to give him and his highly experienced foreign policy advisers the benefit of the doubt on Iraq. Unfortunately, subsequent events have showed that our willingness to trust the judgment of Bush and his team was misplaced.
- Scott McClellan, What Happened (2008)
- The White House had concocted a fake letter from Habbush to Saddam, backdated to July 1, 2001. It said that 9/11 ring leader Mohammed Atta had actually trained for his mission in Iraq—thus showing finally that there was an operational link between Saddam and al Qaeda, something the Vice Presidents Office had been pressing CIA to prove since 9/11 as a justification to invade Iraq. There is no link.

- [Habbush] tells us there are no WMDs. He tells us Saddam's mindset, that he's afraid of the Iranians more than us, afraid of being showed to be a toothless tiger. That is something we ignore.

- "Downtown" refers to the White House. [about Bush]
- Saddam is gone. It's a good thing, but I don't agree with what was done. It was a big mistake. The American government made several errors, one of which is how easy it would be to get rid of Saddam and how hard it would be to unite the country.
- In my opinion, it disrespects the United Nations. It doesn't take into account what the rest of the world thinks. And I think this is serious.
- To a certain extent Saddam Hussein's departure was a positive thing. But it also provoked reactions, such as the mobilization in a number of countries, of men and women of Islam, which has made the world more dangerous.
- Cronyism and corruption are major factors in Iraq's downward spiral.
- Paul Krugman, "What Went Wrong?", New York Times (April 23, 2004)
- If you look at those matters, you will come to the conclusion that the attitude of the United States of America is a threat to world peace. Because what America is saying is that if you are afraid of a veto in the Security Council, you can go outside and take action and violate the sovereignty of other countries. That is the message they are sending to the world. That must be condemned in the strongest terms." – Nelson Mandela .
- The option of war can appear initially to be the most rapid. But let us not forget that after winning the war, peace must be built.
- Who will demand accountability for the failure of our national political leadership involved in the management of this war? They have unquestionably been derelict in the performance of their duty. In my profession, these types of leaders would immediately be relieved or court martialed.
- We want to say to America: Is it worth it to you? Won't you have have, afterward, decades of hostility in the Islamic world?

- When war, as in these days in Iraq, threatens the fate of humanity, it is ever more urgent to proclaim, with a strong and decisive voice, that only peace is the road to follow to construct a more just and united society. Violence and arms can never resolve the problems of man.
- Stewart: And the letter says literally in it Mohammad Atta did train in Iraq, and the uranium thing. Did anyone think it was weird that the letter combined the two things that were in question, that in the letter it said, Oh, and he did buy uranium from Niger...?
Suskind: … It was an overreach moment. The letter popped up. Tom Brokaw did it on Meet the Press. William Safire writes about it. A couple days in, about a week in, people are just like, Geez, it's an awful lot in one letter. And that overreach kind of revealed it to be fraudulent.
Stewart: Why didn't anyone pursue it at that time, the fraudulent nature of it? Why did that just fall away?
Suskind: It was hard to get at. It's a closely held thing, and this is an operation through the CIA. You need someone who's going to stand up in daylight and say, Hey, this is what happened.
Stewart: Your source in the CIA, Richard?
Suskind: He's one of the folks.
Stewart: He now says, I never said that; I was just kidding around. What's the situation with that?
Suskind: He's a good guy. All the [sources] involved here are good guys, walking around with a kind of lump in their chest for awhile. I'm sympathetic to all the sources. They're under a lot of pressure. In this particular part of the book, there are a lot of disclosures, but this one, the White House is obviously intensely interested in, since there may be illegality that has constitutional consequences.
Stewart: That is maybe the nicest way of saying "impeachment" I think I've ever heard in my life.

- Barack Obama became the fourth consecutive U.S. president to order air strikes in Iraq.
President George Bush went into Iraq in 1991 during the Gulf War under the auspices of a U.N. Security Council resolution against the Iraqi invasion of Kuwait and with a resolution authorizing the use of military force (AUMF) from Congress. In the late 1990s, President Bill Clinton ordered airstrikes in Iraq in 1998, claiming Saddam Hussein had been thwarting U.N. weapons inspectors, sans Congressional authorization, arguing the strikes were a temporary measure covered by the War Powers Act. In 2003, under the pretext of problems with the treatment of U.N. weapons inspectors and using multiple U.N. Security Council resolutions to justify the action, President George W. Bush ordered an invasion of Iraq. He, too, had an AUMF, pinned on U.N. Security Council resolutions worried about weapons of mass destruction (WMD). Last year President Obama reinserted the U.S. military into Iraq to combat ISIS.
