United States-led Iraq War

Fifteen votes to nothing was achieved by a text ambiguous enough that Washington read it as authorising force and France read it as requiring a second resolution. Unanimity was purchased with a deferred disagreement, and the disagreement arrived four months later.

Inspectors visited hundreds of sites and found no stockpiles, and the finding did not alter the decision. Intelligence and inspection were being used to support a policy already chosen, and disconfirming evidence was treated as evidence of concealment.

A great power invaded a state that had not attacked it and that most assessments judged unable to do so. The war is the clearest case in modern history of preventive action, undertaken because the capability existed and the perceived risk of waiting was judged higher.

The regime fell in three weeks and the state fell with it, because no plan existed for the second. Military victory and political control are different objectives requiring different forces, and only one had been prepared for.

Dissolving the army put several hundred thousand trained, armed and unemployed men outside the new order, and the insurgency recruited from them. Destroying the defeated state's institutions without replacing them creates the opposition you will then fight.

Attacking the United Nations removed the one organisation with the standing to broker a political process and the expertise to run an election. It was a strategic choice by the attackers, and it succeeded: the organisation withdrew and never returned at scale.

Destroying a shrine was calculated to provoke reprisals and it worked precisely as intended, producing killings, expulsions and the sectarian partition of Baghdad. Provocation is an effective strategy where communities are already armed and the state cannot restrain them.

The withdrawal followed an agreement signed with a government that would not grant immunity to remaining troops, and three years later much of northern Iraq fell to Islamic State. The war's consequences did not end with the departure and were not confined to Iraq.

The United States was going to invade regardless, and the Council process was pursued to gather allies rather than to obtain permission. Where one state's preponderance is this great, institutions are used for legitimacy and are discarded when they do not supply it.

Saddam had allowed enough ambiguity about his capabilities to deter Iran while denying enough to avoid provoking the United States, and the position was untenable once Washington had decided. A deterrence posture built on ambiguity fails when one audience stops believing it.

Nothing in the balance of power required this. Iraq had been contained for twelve years by sanctions, inspections and no-fly zones, and was militarily weaker than in 1991. Unipolarity removes the constraint that would ordinarily prevent a war of choice.

Removing the region's counterweight to Iran produced the strategic result the first Bush administration had predicted in 1991. Balances that took decades to construct can be dismantled in weeks, and the consequences run for decades afterwards.

The orders removed the only organisations capable of providing security in a country the coalition had insufficient troops to police. A vacuum was created deliberately and then filled by militias, criminal networks and eventually foreign fighters.

The organisation was targeted because it was seen as an adjunct of the occupation, having passed resolutions recognising the coalition's authority. Neutrality is a perception held by others rather than a status one declares, and once it has been lost it cannot be recovered by issuing statements, which the organisation discovered over the following decade in several other theatres.

With no authority able to protect either community, each armed for its own defence and each armament frightened the other. The classic security dilemma operated at neighbourhood level, and it produced a civil war within months.

The principal strategic beneficiary was Iran, which acquired a friendly government in Baghdad and a corridor toward the Mediterranean. The invasion produced precisely the regional outcome its critics had predicted and its architects had dismissed, which is that removing Iraq as a counterweight would hand the Gulf's balance to the state the United States most opposed.

Blair needed a Council resolution for domestic reasons that Bush did not, which is why Britain pushed hardest for the diplomatic route. Domestic requirements of one ally shaped the coalition's whole approach to the United Nations.

Blix reported to the Council in public sessions that were broadcast and analysed worldwide, and the reports did not support the case being made. Transparency in the inspection process created a public record that the war's proponents then had to argue around.

Millions demonstrated in European capitals and several allied governments refused to participate, while others joined against their publics' clear preference. Democratic opposition was extensive and did not prevent the war, which is a fact worth stating plainly.

Ministries, museums and hospitals were looted while the oil ministry was guarded, and the images shaped Iraqi perceptions of the occupation from the first week. What an occupier protects tells the population what it values.

De-Baathification reached teachers, engineers and administrators who had joined the party to hold a job, not to support the regime. Applying a political test to an entire professional class removed the people needed to run the country.

Vieira de Mello was the organisation's most capable senior official and had been sent reluctantly, and his death removed the individual most likely to have shaped a political transition. Individuals matter in institutions with thin senior ranks.

The 2005 constitution and elections had produced a government along sectarian lines with ministries controlled as communal fiefs, including their own armed units. Institutional design that allocates power by community makes the state a participant in communal conflict.

Iraq acquired competitive elections, a free press and a parliament, together with corruption, sectarian allocation and periodic collapse. The democratic outcome was real and it was not what had been promised, and both statements are true.

The resolution's serious consequences formula had been used before and its meaning was contested precisely because it had no agreed content. Constructive ambiguity allows agreement now at the price of a fight later, and the price here was the Council's authority.

UNMOVIC had access, aerial surveillance, interviews and no fixed deadline, and it was working. Withdrawing an inspection regime that was functioning in order to invade is the clearest indication of what the process was actually for.

The coalition was assembled bilaterally, state by state, outside any standing institution, and several members contributed token forces for political reasons. Coalitions of the willing are assembled to substitute for authorisation, and what they supply is a list of names rather than the legitimacy that a Council mandate confers. The distinction was obvious to every government that declined to join.

Government collapsed entirely: no police, no courts, no payroll, no electricity administration. Occupying powers carry an obligation to restore public order under the Hague Regulations, and the capacity to discharge it had deliberately not been deployed, because the plan assumed an Iraqi administration would remain in place to be inherited.

The two orders were issued within a week by an authority two weeks old, reversing planning done by other agencies. Institutional process failed comprehensively: the decisions were taken by few people, quickly, against prior analysis, and were irreversible.

The building had been deliberately left lightly protected so as not to appear allied with coalition forces. A security decision taken to preserve the appearance of independence proved fatal, and the organisation's entire security posture was rebuilt afterwards.

The eventual reduction in violence came from a combination of additional troops, the Anbar tribal alignment and the completion of much of the sectarian separation. Attributing it to a single measure is a persistent error in how the period is analysed.

The status of forces agreement was negotiated bilaterally and set the withdrawal date, which the American government then had to observe. A treaty with a client state constrained a superpower's deployment, which is an unusual and instructive outcome.

Whether force required a further decision was a question about the Charter's rules on the use of force, argued by every government in legal terms. That the argument was conducted in law rather than in interest matters, even where the law did not determine the outcome.

The Council's own instrument was reporting that its concerns were not being borne out, and members divided on what followed. International society had built machinery for exactly this question and then did not accept its answer.

The Secretary-General later stated that the war was illegal under the Charter, and no plausible authorisation existed. A permanent member of the Council using force in these circumstances damaged the rule more than any weak state could have.

Occupation law imposes duties to maintain public order and safety and to respect existing laws, and the Coalition Provisional Authority instead legislated extensively. International society has rules for this situation and they were treated as an obstacle.

Occupying powers are required to respect the laws in force unless absolutely prevented, and reconstructing a state's political order goes well beyond that. The occupation exceeded what the law of occupation contemplates, which is why the legal basis was contested throughout.

Attacking international officials engaged in humanitarian and political work breached a protection international society had assumed rather than enforced. After Baghdad that assumption could no longer be made anywhere, and humanitarian operations from Afghanistan to Somalia rebuilt themselves around armed protection, remote management and a far narrower physical presence.

The occupying powers held responsibility for protecting the population and were unable to discharge it, while the war's civilian toll ran into the hundreds of thousands. The gap between obligation and capacity defines the occupation's record.

A war launched without Council authorisation, on a case that proved unfounded, damaged the credibility of the states that argued for it whenever they later invoked international law. That cost has been visible in every subsequent crisis.

The case was built on weapons of mass destruction, a category that fused nuclear, chemical and biological capabilities of very different significance. That conflation made a chemical shell and a nuclear device sound equivalent, and it carried much of the argument.

Powell's presentation to the Council in February combined satellite images, intercepts and diagrams into a case that persuaded much of the American public. The performance of evidence, by a figure of unusual credibility, did work no document could have done.

The war was justified by connecting Iraq to the attacks of 2001 in a way the evidence never supported and much of the public nonetheless believed. A framing established after September 2001 made an unrelated war intelligible as part of a response.

The toppling of the statue in Firdos Square was staged for cameras with a small crowd and became the war's defining image. What the moment was made to represent, liberation greeted with joy, shaped expectations that the following months destroyed.

Baathist and Sunni were treated as interchangeable in practice, so a policy aimed at a party was experienced as directed at a community. That identification did more than any other decision to produce the sectarian conflict that followed.

The bombing announced that the conflict's participants did not accept the distinction between occupier and international organisation. Once that distinction was rejected in practice by the people with the explosives, humanitarian actors lost the protection the category had quietly provided for fifty years, and no amount of insisting on it has restored the position.

Iraqi identity had been substantially national before the invasion, and sectarian categories became the primary political fact within three years. Identities are not fixed; they harden under violence, and the hardening here was rapid and largely irreversible.

The war destroyed the domestic consensus for intervention in both Britain and the United States, and the caution in Syria two years later was traced directly to it. Lessons drawn from one war govern the next, whether or not the cases resemble each other.
