The 2003 US-led invasion of Iraq began in a fog of controversy over the issue of the war’s legality, timing and rationale. Distinguished jurists, statesmen/women and others around the globe have added their voices to the din surrounding the issue of legality vs. illegality which today remains unanswered and without definitive conclusion.
UN Resolutions, Charter and Laws
The United Nations Security Council had passed over 17 resolutions dealing with the situation in Iraq prior to the US-led invasion in 2003. The first was resolution 660, which dealt with the initial Iraqi invasion of Kuwait. The following resolution, 661, specifically mentioned Chapter VII of the UN Charter, which states in part in Article 39:
The Security Council shall determine the existence of any
threat to the peace, breach of the peace, or act of aggression and shall make recommendations, or decide what measures shall be taken in accordance with Articles 41 and 42, to maintain or restore international peace and security.
The Security Council, acting under its obligation to restore international peace and security in the region, ordered a package of measures put in place including comprehensive sanctions to force Iraq to withdraw from Kuwait.
Because Iraq did not withdraw from Kuwait and as a member of the United Nations was in violation of international law, the UN Security Council subsequently passed resolution 678, which again stated that the council acting under Chapter VII:
- Authorizes Member States co-operating with the Government of Kuwait, unless Iraq on or before 15 January 1991 fully implements, as set forth in paragraph 1 above, the above-mentioned resolutions, to use all necessary means to uphold and implement resolution 660 (1990) and all subsequent relevant resolutions and to restore international peace and security in the area;
Following the successful ejection of Iraq forces from Kuwait the UN Security Council passed resolution 687 which "welcomed the restoration to Kuwait of its sovereignty, independence and territorial integrity." The resolution also imposed conditions on Iraq for ending the war, most of which concerned Iraqi obligations to end its weapons of mass destruction (WMD) program. The relevant articles of the resolution are as follows:
- Decides that Iraq shall unconditionally accept the destruction, removal, or rendering harmless, under international supervision, of:
(a) All chemical and biological weapons and all stocks of agents and all related subsystems and components and all research, development, support and manufacturing facilities;
(b) All ballistic missiles with a range greater than 150 kilometres and related major parts, and repair and production facilities;
Resolution 687 goes on to state:
- Declares that, upon official notification by Iraq to the Secretary-General and to the Security Council of its acceptance of the provisions above, a formal cease-fire is effective between Iraq and Kuwait and the Member States cooperating with Kuwait in accordance with resolution 678 (1990);
- Decides to remain seized of the matter and to take such further steps as may be required for the implementation of the present resolution and to secure peace and security in the area.
Resolution 687, as stated above, finds that the UN Security Council "remains seized of the matter" of Iraq’s compliance with all relevant UN Security Council resolutions and the conditions imposed as a result of the passage of those resolutions. It also states that it can "take such further steps" as are necessary "to secure peace and security in the area.
Following a long period of low-level hostility between Iraq and the United States, the US acting with Great Britain as the armed party responsible for enforcing UN resolutions regarding Iraq began pushing for additional resolutions arguing that Iraq was in violation of its obligations under previous UN Security Council resolutions, in particular those named above.
The result was UN Security Council resolution 1441, which stated the following:
Further recalling that its resolution 687 (1991) imposed obligations on Iraq as a necessary step for achievement of its stated objective of restoring international peace and security in the area,
- Decides that Iraq has been and remains in material breach of its obligations under relevant resolutions, including resolution 687 (1991), in particular through Iraq's failure to cooperate with United Nations inspectors and the IAEA, and to complete the actions required under paragraphs 8 to 13 of resolution 687 (1991);
- Recalls, in that context, that the Council has repeatedly warned Iraq that it will face serious consequences as a result of its continued violations of its obligations
Supporters of the argument that the Iraq was legal tend to rely on UN Security Council resolutions 678, 687 and the following resolution 1441. In particular the arguments put forward, in public, by British Attorney General Lord Goldsmith, who stated in a written parliamentary answer that the combined resolutions mentioned above gave the US-led coalition authority under international law to invade Iraq. In his advisory opinion he stated the following:
Authority to use force against Iraq exists from the combined effect of resolutions 678, 687 and 1441. All of these resolutions were adopted under Chapter VII of the UN Charter which allows the use of force for the express purpose of restoring international peace and security.
In resolution 687, which set out the ceasefire conditions after Operation Desert Storm, the Security Council imposed continuing obligations on Iraq to eliminate its weapons of mass destruction in order to restore international peace and security in the area. Resolution 687 suspended but did not terminate the authority to use force under resolution 678.
- A material breach of resolution 687 revives the authority to use force under resolution 678.
- In resolution 1441 the Security Council determined that Iraq has been and remains in material breach of resolution 687, because it has not fully complied with its obligations to disarm under that resolution.
- The Security Council in resolution 1441 gave Iraq "a final opportunity to comply with its disarmament obligations" and warned Iraq of the "serious consequences" if it did not (Goldsmith).
These arguments, relying on the UN resolutions mentioned above, were echoed by the legal experts representing the US government as well as that of Australia. All relied on the language of continuance emanating from resolution 687 and then buttressed by UN Security Council resolution 1441, in particular the language of "material breach."
Those against the war take issue with the arguments by the states and their defenders arguing for the war in Iraq.
The "revival argument" states that a case can be made for war under existing UN Security Council resolutions and specifically mentions resolutions 678 and 687. Lord Goldsmith in his opinion marked "Secret" says the following regarding what is called "the revival argument."
Law Officers have advised in the past that, provided the conditions are made out, the revival argument does provide a sufficient justification in international law for the use of force against Iraq. That view is supported by an opinion given in August 1992 by the then UN Legal Counsel, Carl-August Fleischauer.
However, the UK has consistently taken the view (as did the Fleischauer opinion) that, as the ceasefire conditions were set by the Security Council in resolution 687, it is for the Council to assess whether any such breach of those obligations has occurred.
I remain of the opinion that the safest legal course would be to secure the adoption of a further resolution to authorise the use of force. I have already advised that I do not believe that such a resolution need be explicit in its terms. The key point is that it should establish that the Council has conduced that Iraq has failed to take the final opportunity offered by resolution 1441, as in the draft which has already been tabled (Goldsmith).
Lord Goldsmith goes on to state, regarding the issue of Iraq and whether a "reasonable case" can be made for war:
"But a "reasonable case" does not mean that if the matter ever came before a court I would be confident that the court would agree with this view."
Looking further at UN resolution 1441 one can see clearly strong language used in this resolution, including "material breach," "final opportunity" and "full compliance." However unlike UN Security Council resolution 678, resolution 1441 does NOT mention "all necessary means" anywhere or feature any text authorizing any UN member to use force against Iraq.
The resolution declares Iraq in "material breach" but then does not anywhere provide a remedy to mend that "material breach." When a lawmaking body, such as the UN Security Council, finds a party in breach it would then typically assess a penalty for that breach. In the case of Iraq the United States and its coalition allies took it upon themselves to remedy that breach using the argument that older UN Security Council resolutions authorized them to do so.
In late November 2003 Richard Pearle, a prominent neo-conservative and architect of the Iraq war, said this in London:
"...international law ... would have required us to leave Saddam Hussein alone", and this would have been morally unacceptable... I think in this case international law stood in the way of doing the right thing."
Here you have an architect of the war, a member of the Pentagon defense review board which advises the US Secretary of Defense, stating clearly that the war was illegal but offering up the rationale that when international law is inconvenient a state can simply break the law.
In 2004 UN Secretary-General Kofi Annan statedthat the Iraq war was illegal under the UN charter:
"I have indicated it was not in conformity with the UN charter. From our point of view and from the charter point of view it was illegal."
While the Secretary-General is not a judge his opinion does carry weight internationally.
The United States and its coalition allies relied in many ways on the concepts of a "just war" in stating that Saddam Hussein’s regime was a bad one and that it posed a danger to peace and security in the area.
But the idea of a "just war" disappeared more than 300 years ago. As Shaw states, "States were sovereign and legal and no state could presume whether another’s cause was just or not." For the purposes of this report "just war" is non-important, "legal war" is.
Further arguments in opposition to the war exist in a reading of the UN charter. Section 2 (3) and (4) state:
- All Members shall settle their international disputes by peaceful means in such a manner that international peace and security, and justice, are not endangered.
- All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations.
These principles, that a state must settle disputes peacefully first, are a matter of treaty law to which all UN members ascribe when they sign and accept membership in the United Nations. Furthermore the principle of settling disputes peacefully could be considered to now be a rule of customary international law.
The 1970 Declaration on Principles of International Law states the following:
The principle that States shall refrain in their international ~ relations from the threat or use of force against the territorial integrity or political independence of any State or in any other manner inconsistent with the purposes of the United Nations
Every State has the duty to refrain in its international relations from the threat or use of force against the territorial integrity or political independence of any State, or in any other manner inconsistent with the purposes of the United Nations. Such a threat or use of force constitutes a violation of international law and the Charter of the United Nations and shall never be employed as a means of settling international issues.
A war of aggression constitutes a crime against the peace, for which there is responsibility under international law (Shaw 1019).
In its war against Iraq the US operated on the principle that Iraq should be punished through use of force and specifically stated that its goal was to overthrow the regime of Saddam Hussein. While the 1970 declaration is a UN General Assembly resolution (2625) and not one from the UN Security Council it does add to the weight of international opinion.
Under a reading of the UN charter and subsequent UN resolutions dealing with the situation in Iraq the US-led attack against Iraq was illegal under international law. The US-led attack violated the UN charter section 2 (3) & (4). The US did not posses the authority on it own to enforce UN Security Council resolutions regarding Iraq.
Customary International Law – Interceptive/Anticipatory Self-defense
The US claimed Saddam Hussein posed a "grave threat to peace" and thus could make a claim that it was exercising its right to self-defense under Article 51 of the UN charter and customary international law (White House, Oct 7, 2002). This theory would be known as "interceptive self-defense" and would depend on the evidence shown of an imminent threat.
The Caroline Affair of 1838 established as a rule of customary international law:
...the principle of "anticipatory self-defense" in international politics, which holds that it may be justified only in cases in which the "necessity of that self-defence is instant, overwhelming, and leaving no choice of means, and no moment for deliberation."
Did the United States have a clear and compelling case for the use of interceptive or anticipatory self-defense?
Arguing in the law journal of the International Law Department of the University of Miskolic, law professor Louise-Phillipe Rouillard wrote the following:
The existence of a right to anticipatory self-defence can be established and there certainly are clear and imminent dangers that must be pre-emptively addressed. But they must be so addressed within the strict and narrow confines of the exhaustion of all alternative means, the necessity of its actions being established by the immediacy of the danger, and must be proportional to the threat. Regardless of the excuses given so far toward the extension of this right, none have either been conclusive or even remotely convincing. None have been accepted so far by the international community and certainly none should be.
How, exactly, did Saddam Hussein present an "imminent threat" to the United States when in July 2001 (then) National Security adviser Condoleeza Rice said the following:
"We are able to keep arms from him. His military forces have not been rebuilt."
Yet the evidence indicated, in statements from US administration officials and the memos mentioned below, that the US had already decided to "go after" Saddam Hussein and Iraq. Clearly the doctrine of "anticipatory" or "interceptive self-defense" do not apply to a war that was years in the making before it was launched.
The US also violated customary international law by not seeking to settle its differences with Iraq peacefully and by seeking to use the cover of the UN, which it ultimately did not receive, to wage war against Iraq when it had already decided, on the basis of secret memos published in the Sunday Times of London, to go to war against Iraq more than a year before the actual invasion began.
Military action was now seen as inevitable. Bush wanted to remove Saddam, through military action, justified by the conjunction of terrorism and WMD. But the intelligence and facts were being fixed around the policy. The NSC had no patience with the UN route, and no enthusiasm for publishing material on the Iraqi regime's record.
The Defence Secretary said that the US had already begun "spikes of activity" to put pressure on the regime. No decisions had been taken, but he thought the most likely timing in US minds for military action to begin was January, with the timeline beginning 30 days before the US Congressional elections (Manning).
These memos, which were notes sent between members of the UK foreign policy team, clearly indicate that the US planned to take military action against Saddam Hussein’s regime regardless of whether it received UN permission or not. The war was a premeditated act of aggression unsanctioned by international law. The war was illegal.
Terrorism
The United States was struck on September 11, 2001 with a horrendous attack which killed nearly 3,000 people. Understandably the United States government and its people were traumatized by this attack and vowed to take all necessary measures to prevent another attack from occurring.
Using this rationale could the fact that Saddam Hussein’s government had expressed support for and glee about the attacks be used as a basis for attacking Iraq? Could the fact that Saddam Hussein, in providing cash payments to Palestinian suicide bombers in the West Bank, Gaza and Israel in violation of UN Security Council resolution 687, Section H (32) serve as a legal basis for the US-led attack on Iraq?
On September 16, 2001 Vice-President Dick Cheney, when asked of the US had any evidence linking Saddam Hussein to the 9/11 attacks, said the following:
"No."
There was no evidence linking Saddam Hussein to any attack on the United States immediately after 9/11 or before the invasion of Iraq in March 2003. Nor has there been any evidence presented since the invasion linking Iraq to 9/11 or any terrorist attack on the United States or its citizens.
Saddam Hussein was in violation of his obligations under UN Security Council resolution 687 by vocalizing support for the September 11th attacks as well as providing support to those carrying out terrorist attacks in Israel or the occupied territories. Nonetheless the US was bound by customary international law in responding to these acts – specifically the principle of proportionality.
The International Court of Justice (ICJ) ruled in the case Nicaragua vs. US there exists "a specific rule whereby self-defense would warrant only measures which are proportional to the armed attack and necessary to respond to it, a rule well established in customary international law."
The attack on Iraq by the US-led coalition could never be justified using the rationale that Saddam Hussein was supporting international terrorism. The US could show no direct injury from this support and even if it could its response would be constrained by the principle of proportionality, which is an established rule of customary international law. An invasion of Iraq using the rationale of Iraqi support for terrorism would also be illegal under international law.
Conclusion
This report has focused on the legal basis for and against the US-led attack on Iraq in 2003. The issue of the non-discovery of Iraq’s WMD program has deliberately been left out because that issue does not relate to illegality of the war, rather bad or forged intelligence on the part of the US and its allies. Whether Iraq was in possession of WMDs, which it was not, is inconsequential to the root issue of legality.
As stated previously – the US and its coalition did not posses the legal authority under the UN charter or relevant UN Security Council resolutions to invade Iraq. Nor could a persuasive and legally defensible case for invasion be made under customary international law – specifically self-defense or using the doctrine of imminent threat. A case for invading Iraq also does not exist under the threat of terrorism, pre or post 9/11.
In short – while defenders of the US invasion can muster imaginative and varied arguments to support their case they are, at the heart of every argument, incorrect. The Iraq war was not legal. Subsequent UN Security Council resolutions have authorized coalition forces in Iraq but that does in no way change the fact that the war as carried out by the US-led coalition was illegal under both treaty law (UN charter) and customary international law.
