What this dot point is asking

NESA expects you to explain why Saddam Hussein invaded Kuwait, how the invasion happened, and how the international community responded. Strong answers integrate the long-term and short-term causes (debt, oil prices, territorial claims, Glaspie meeting), the invasion itself, the annexation, the UN Security Council resolutions, and the formation of the US-led Coalition.

The answer

The post-war Iraq problem

Iraq emerged from the Iran-Iraq War (ceasefire 20 August 1988) with an army of around 1 million but a wrecked economy. Foreign debt totalled around 80 billion US dollars. Annual debt service exceeded annual oil revenues. The regime needed money.

The major creditors were the Gulf monarchies (Saudi Arabia and Kuwait, around 30 billion each), Western governments, and Soviet bloc arms suppliers. Saddam framed the war as having defended the Arab world from Iranian revolutionary expansion and argued the Gulf loans should be cancelled.

Oil prices and Kuwait

Iraq needed oil at around 25 US dollars per barrel to service debt and rebuild. Through 1989 and 1990 Kuwait and the United Arab Emirates consistently exceeded their OPEC production quotas, pushing prices down. By July 1990 oil traded at around 14 US dollars per barrel. Every dollar below 25 cost Iraq about 1 billion US dollars per year.

The Rumaila oilfield straddles the Iraq-Kuwait border. Iraq accused Kuwait of slant drilling under the border to extract Iraqi oil; the claim was largely unsupported by evidence.

Diplomatic build-up: May to July 1990

The Arab Cooperation Council summit at Baghdad (28-30 May 1990) heard Saddam attack Kuwait. The 16 July 1990 letter from Foreign Minister Tariq Aziz accused Kuwait of stealing oil. On 17 July 1990 Saddam delivered a speech threatening "effective action."

The Jeddah negotiations (31 July to 1 August 1990) between Iraqi delegate Izzat Ibrahim al-Douri and Kuwaiti Crown Prince Sheikh Saad al-Abdullah broke down after one day. Iraq invaded the next morning.

The Glaspie meeting

US ambassador April Glaspie was summoned to meet Saddam on 25 July 1990. The Iraqi transcript records Glaspie saying:

"I have direct instruction from the President to seek better relations with Iraq. We have no opinion on the Arab-Arab conflicts, like your border disagreement with Kuwait."

Glaspie did warn Saddam against military action but emphasised hopes for diplomatic resolution. Saddam read the meeting as confirming US disinterest.

The invasion

At 02:00 on 2 August 1990 Iraqi forces crossed the Kuwait border at multiple points. The Republican Guard's Hammurabi, Medina, and Tawakalna divisions led. Kuwait City fell within 12 hours. The Dasman Palace fell after a firefight in which Sheikh Fahd al-Sabah, the Emir's brother, was killed.

Emir Jaber al-Sabah and Crown Prince Saad evacuated to Saudi Arabia. Around 350,000 expatriate workers fled overland. Foreign nationals including Westerners were held as "human shields" at strategic sites in Iraq through the autumn.

Annexation

Iraq initially announced a provisional government under "free Kuwaitis" (4 August 1990). On 8 August 1990 Saddam declared the "comprehensive eternal merger" of Kuwait with Iraq. On 28 August Kuwait was declared the "nineteenth province" of Iraq.

The UN response

Resolution 660 (2 August 1990)
14-0 with Yemen abstaining. Condemned the invasion and demanded immediate withdrawal.
Resolution 661 (6 August 1990)
Imposed comprehensive sanctions: a total trade embargo on Iraq and Kuwait.
Resolution 662 (9 August 1990)
Declared the annexation null and void.
Resolution 665 (25 August 1990)
Authorised naval enforcement of the sanctions.
Resolution 678 (29 November 1990)
Authorised "all necessary means" if Iraq had not withdrawn by 15 January 1991. The vote was 12-2 (Cuba and Yemen against, China abstaining). This was the legal basis for war.

The Coalition

President George H. W. Bush declared on 5 August 1990 that "this will not stand". Secretary of State James Baker and National Security Adviser Brent Scowcroft built the Coalition through August to November.

The Coalition eventually included 35 nations. The United States provided around 540,000 troops at peak. Britain contributed 53,000; France 18,000; Egypt 36,000; Syria 14,000; Saudi Arabia 100,000; Kuwait 7,000. Australia contributed two frigates and a supply ship. Japan and Germany contributed 13 billion and 6 billion US dollars respectively.

The Arab participation was secured at the Cairo Arab League summit (10 August 1990), which voted 12-3 to deploy Arab forces. Operation Desert Shield deployed forces to Saudi Arabia from 7 August 1990.

Last diplomacy

US-Iraq talks between Baker and Aziz at Geneva on 9 January 1991 lasted six hours and produced nothing. The Iraqi National Assembly voted on 14 January 1991 to authorise war. The UN deadline expired at midnight on 15 January 1991 New York time.

Historiography

Lawrence Freedman and Efraim Karsh (The Gulf Conflict 1990-1991, 1993) is the standard diplomatic history.

Michael Gordon and Bernard Trainor (The Generals' War, 1995) is the operational standard.

F. Gregory Gause III (The International Relations of the Persian Gulf, 2010) places the invasion in regional structural context.

The central interpretive tension is over agency. Lawrence Freedman and Efraim Karsh read the invasion as a calculated act of rational coercion that went wrong - Saddam's gamble undone by a misjudgement of the international response, with the Glaspie meeting a deterrence failure rather than a "green light". F. Gregory Gause III shifts the weight from personality to structure, arguing the post-war financial crisis and the Gulf balance of power made some Iraqi move against Kuwait likely whoever sat in Baghdad. Where Freedman foregrounds Saddam's choices and miscalculation, Gause foregrounds the structural pressures that constrained them.

How to read a source on this topic

Sources commonly include the Glaspie transcript, the 17 July 1990 Saddam speech, the UN Security Council resolution texts, Bush 41's 5 August "this will not stand" remarks, and images of Kuwaiti tanks burning in Kuwait City.

First, weigh the Glaspie meeting carefully. The "green light" interpretation is overstated by Saddam apologists; Glaspie did warn against military action. But she lacked clear authority to threaten consequences.

Second, note the Soviet position. Without Soviet acquiescence in the Security Council, Resolution 678 could not have passed. The end of the Cold War made this war possible.

Examples in context

Example 1. The April Glaspie meeting (25 July 1990). US Ambassador Glaspie told Saddam the United States had "no opinion on the Arab-Arab conflicts, like your border disagreement with Kuwait." The transcript, leaked to the New York Times on 23 September 1990, was used by critics to argue America gave a green light. Pierre Razoux and Lawrence Freedman (with Efraim Karsh, The Gulf Conflict, 1993) treat the meeting as a diplomatic misstep but not a green light, in the context of Saddam's $14 billion Kuwaiti debt and Rumaila oilfield dispute.

Example 2. UN Security Council Resolution 678 (29 November 1990). Authorised member states to use "all necessary means" to expel Iraq if Saddam did not withdraw by 15 January 1991. Lawrence Freedman emphasises the unprecedented Soviet acquiescence and Chinese abstention as the moment Bush's New World Order seemed feasible. The Coalition reached 35 nations; Japan and Germany contributed funding rather than troops, beginning a debate about post-Cold War burden sharing.

Practice (NESA)15 marksAssess the causes of the Iraqi invasion of Kuwait in August 1990.
Show worked answer →

Needs criteria, dated evidence, judgement on relative weight.

Thesis
The invasion was Saddam Hussein's calculated solution to multiple post-Iran-war problems. Debt, oil prices, and territorial claims were proximate causes; misreading of US signals was the trigger.
Debt
Iraq emerged from the Iran-Iraq War in August 1988 with around 80 billion US dollars in foreign debt, including around 14 billion to Kuwait. Kuwait refused to forgive the loans.
Oil prices
Iraq's reconstruction needed oil at around 25 US dollars per barrel. Kuwait and the UAE consistently exceeded their OPEC quotas through 1989-1990, driving prices to around 14 US dollars by July 1990. Saddam's 18 July 1990 letter to the Arab League accused Kuwait of "economic warfare."
Territorial claims
Iraq claimed Kuwait had stolen oil from the Rumaila field by slant drilling. Older claims that Kuwait was historically part of Iraqi Basra province were revived. Iraq demanded Bubiyan and Warbah islands.
April Glaspie meeting
US ambassador April Glaspie met Saddam on 25 July 1990. The transcript shows her saying the US had "no opinion on Arab-Arab conflicts." Saddam read this as a green light.
The invasion
Iraqi Republican Guard units crossed the border at 02:00 on 2 August 1990. Kuwait City fell within 12 hours. Emir Jaber al-Sabah fled to Saudi Arabia. Iraq announced annexation as the nineteenth province on 8 August.
Conclusion
Debt was decisive; oil prices and territorial claims provided justification; Glaspie ambiguity provided green light.
Practice (NESA)6 marksExplain how the United Nations responded to the Iraqi invasion of Kuwait in August 1990.
Show worked answer →

A 6-mark "explain" needs three or four developed responses.

Resolution 660 (2 August 1990)
Passed within hours of the invasion (14 votes to 0, Yemen abstaining). Condemned the invasion and demanded immediate Iraqi withdrawal. The speed reflected the post-Cold-War Soviet-American cooperation.
Resolution 661 (6 August 1990)
Imposed comprehensive economic sanctions on Iraq: ban on imports from Iraq and Kuwait, ban on exports except for medical supplies and food in humanitarian circumstances.
Resolution 662 (9 August 1990)
Declared the Iraqi annexation of Kuwait "null and void" and called on states not to recognise it. No country recognised the annexation.
Resolution 678 (29 November 1990)
Authorised member states to use "all necessary means" to enforce the previous resolutions if Iraq did not withdraw by 15 January 1991. 12 votes to 2 (Cuba, Yemen against; China abstaining). This was the legal basis for Operation Desert Storm. Markers reward exact resolution numbers, the 15 January 1991 deadline, and the Soviet-US cooperation context.

Practice questions

Original practice questions graded from foundation to exam level, each with a full worked solution. Try them before revealing the solution.

foundation3 marksOutline three economic grievances that pushed Saddam Hussein towards invading Kuwait in 1990.
Show worked solution →

A 3-mark "outline" wants three distinct, dated grievances in a sentence each.

Debt
Iraq left the Iran-Iraq War (ceasefire August 1988) owing around 80 billion US dollars, including about 14 billion to Kuwait, which refused to forgive the loans.
Oil prices
Iraq needed oil at around 25 US dollars a barrel; Kuwaiti and Emirati overproduction helped push it to around 14 dollars by July 1990, costing Iraq roughly 1 billion dollars a year for every dollar below 25.
The Rumaila field
Iraq accused Kuwait of slant drilling under the border to steal Iraqi oil from the shared Rumaila field.
Marking criteria
1 mark each for three distinct, correctly framed economic grievances; do not simply narrate the invasion.
foundation4 marksExplain how the United Nations Security Council responded to the invasion between August and November 1990.
Show worked solution →

A 4-mark "explain" needs a sequence of resolutions with what each did.

Resolution 660 (2 August 1990)
Passed within hours (14-0, Yemen abstaining); condemned the invasion and demanded immediate withdrawal.
Resolution 661 (6 August 1990)
Imposed comprehensive economic sanctions - a near-total trade embargo on Iraq and occupied Kuwait.
Resolution 662 (9 August 1990)
Declared the annexation 'null and void'; no state recognised the nineteenth-province claim.
Resolution 678 (29 November 1990)
Authorised 'all necessary means' if Iraq did not withdraw by 15 January 1991, providing the legal basis for war.
Marking criteria
1 mark each for correctly dating and explaining four resolutions; reward noting that post-Cold-War Soviet cooperation made the speed and unity possible.
core5 marksSource A (paraphrased, owned): In an address to the Arab League on 18 July 1990, Iraq's leadership accused Kuwait of waging "economic warfare" by deliberately flooding the oil market to keep prices low, and warned that Iraq would not let its people be starved of the revenues they had bled for in the war against Iran. Using Source A and your own knowledge, explain how Iraq justified its actions against Kuwait in 1990. [5 marks]
Show worked solution →

A 5-mark "explain ... using the source" wants the source decoded, then linked to own knowledge.

Decode the source
The 18 July 1990 address frames Kuwait as the aggressor: Iraq casts low oil prices as a hostile act ("economic warfare") and invokes the sacrifice of the Iran-Iraq War to claim a moral debt the Gulf states should repay.
Own knowledge
This rhetoric rested on real grievances: around 80 billion US dollars of debt (about 14 billion to Kuwait), oil at around 14 dollars rather than the 25 Iraq needed, and the Rumaila slant-drilling accusation. Tariq Aziz's 16 July 1990 letter to the Arab League had made the same charges in writing.
The function
The justification recast naked aggression as self-defence of the Arab nation, preparing public opinion for the invasion of 2 August 1990 and the later "nineteenth province" annexation.
Marking criteria
1 mark for decoding the 'economic warfare' framing; 1-2 marks for own knowledge (debt, oil price, Rumaila); 1 mark for linking the Iran-Iraq War sacrifice claim; 1 mark for identifying the propaganda function.
core5 marksSource B (paraphrased, owned): A later historian argues that the 25 July 1990 Glaspie meeting has been wrongly cast as an American "green light"; the ambassador did warn against the use of force, but Washington failed to grasp how close Iraq was to invading and sent no clear deterrent. Using Source B and your own knowledge, assess the usefulness of this interpretation for understanding the causes of the invasion. [5 marks]
Show worked solution →

A 5-mark "assess the usefulness" rewards perspective plus own knowledge, ending in a judgement.

Perspective
Source B is a revisionist reading (the position of Lawrence Freedman and Efraim Karsh) that rejects the conspiratorial "green light" thesis and reframes Glaspie as a failure of deterrence, not collusion - useful for correcting Saddam-apologist accounts.
Corroboration from own knowledge
It fits the record: the Iraqi transcript has Glaspie saying the US had "no opinion on Arab-Arab conflicts", but she also urged a diplomatic settlement and warned against force. Washington misread the May-July build-up (the Aziz letter, the 17 July speech, the failed Jeddah talks).
Limitation
By stressing miscommunication it can understate the structural drivers - debt, oil and the Rumaila dispute - that meant Saddam was likely to act whatever the US signalled.
Judgement
Highly useful for puncturing the green-light myth and foregrounding deterrence failure, but it must be read alongside the economic causes that made the invasion likely regardless.
Marking criteria
1 mark for identifying the revisionist perspective; 1-2 marks for own knowledge on the meeting and build-up; 1 mark for a limitation; 1 mark for a judgement on usefulness.
core6 marksExplain why the Iraqi invasion of Kuwait provoked an unprecedented international response.
Show worked solution →

A 6-mark "explain" needs three or four developed reasons with evidence.

The end of the Cold War
Soviet-American rivalry no longer paralysed the Security Council; Moscow's acquiescence let Resolutions 660 to 678 pass quickly, something impossible a few years earlier.
A clear breach of sovereignty
Iraq did not merely raid Kuwait - it annexed a UN member state outright (the "nineteenth province", 28 August 1990), a naked violation of the UN Charter that was easy to condemn.
Oil and strategic stakes
Iraq now controlled around 20 per cent of world oil reserves and sat on the Saudi border; an Iraqi move into Saudi Arabia would have threatened the global economy, prompting Operation Desert Shield from 7 August 1990.
Coalition diplomacy
Baker and Scowcroft assembled 35 nations and secured Arab participation (Cairo Arab League vote, 10 August 1990) and the funding of Japan and Germany, giving the response legitimacy and breadth.
Marking criteria
1-2 marks for the post-Cold-War context; 1 mark for the annexation as Charter breach; 1 mark for oil/strategic stakes; 1 mark for Coalition diplomacy; reward dated specifics throughout.
exam25 marksEvaluate the extent to which the Iraqi invasion of Kuwait in 1990 was driven by economic pressures rather than Saddam Hussein's miscalculation of the international response.

This is an extended-response/essay. Markers reward a sustained, evidence-based argument that addresses the comparison directly and weaves in historiography - not a narrative.

Band-6 PLAN

  • Thesis. Economic pressure supplied the motive and miscalculation supplied the opportunity: debt, low oil prices and the Rumaila dispute made Saddam determined to act, but it was his misreading of US resolve and the post-Cold-War order that made him believe he could act with impunity. Economics was decisive in explaining why; miscalculation explains why now and in that form.
  • Argument 1 - Economic pressure as the driver. Iraq emerged from the Iran-Iraq War (1988) owing around 80 billion US dollars (about 14 billion to Kuwait), with oil at around 14 dollars against the 25 it needed. Evidence: Tariq Aziz's 16 July 1990 letter and the 18 July 'economic warfare' speech; the Rumaila slant-drilling claim; Kuwait's refusal to forgive debt or cut production.
  • Argument 2 - Miscalculation as the enabler. Saddam misjudged the international reaction: the 25 July Glaspie meeting was read as indifference, and he assumed a divided, post-Cold-War world would not unite against him. Evidence: the speed and unanimity of Resolutions 660 to 678, the 35-nation Coalition, and Soviet acquiescence all blindsided Baghdad.
  • Argument 3 - The interaction. The two are not rivals but a sequence: economic desperation set the goal (seize Kuwait's wealth and oil), while miscalculation removed the perceived risk. Saddam also miscalculated militarily, expecting to keep Kuwait as a fait accompli.
  • Historiography. Lawrence Freedman and Efraim Karsh (The Gulf Conflict 1990-1991, 1993) read the invasion as rational coercion gone wrong - a calculated gamble undone by a misjudged international response. F. Gregory Gause III (The International Relations of the Persian Gulf, 2010) places it in regional structural context, stressing the post-war financial crisis and the Gulf balance of power over personality.
  • Judgement. Economic pressure was the necessary cause - without the debt and oil crisis there is no invasion - but miscalculation was the permissive cause that turned grievance into action in August 1990. Most weight to economics; but the timing and recklessness are unintelligible without the misreading of the international response.

MODEL PARAGRAPH (Argument 2)

If economic desperation set Saddam's goal, it was his misreading of the wider world that convinced him the goal was within safe reach. The clearest sign is the 25 July 1990 meeting with US ambassador April Glaspie, whose remark that Washington had "no opinion on Arab-Arab conflicts" Saddam folded into a broader assumption that a distracted, post-Cold-War America would not fight for a small Gulf monarchy. He was catastrophically wrong. Within hours of the 2 August invasion the Security Council passed Resolution 660, and over the following months Resolutions 661, 662 and 678 followed with a speed and unanimity that the Cold War had always prevented - made possible by Soviet acquiescence that Saddam had not factored in. As Lawrence Freedman and Efraim Karsh argue, the invasion is best understood as rational coercion gone wrong: Saddam's grievances were real, but his gamble rested on a deterrence failure and a misjudgement of the new international order, not on any green light. The economics told him to move; the miscalculation told him it was safe.

Marker's note. A band-6 response sustains the comparison throughout (always weighing economic pressure against miscalculation), anchors every claim in dated evidence, deploys at least two historians in genuine tension (Freedman/Karsh's rational-coercion reading vs Gause's structural-regional reading), and reaches a judgement rather than listing causes. Narrating the invasion without arguing the relative weight of the two factors caps the response in the middle bands.

exam25 marksTo what extent was the international response to the invasion of Kuwait shaped more by the end of the Cold War than by the principle of collective security?
Show worked solution →

This is an extended-response/essay. Markers reward a sustained, evidence-based argument that addresses the question directly and weaves in historiography - not a narrative.

Band-6 PLAN

  • Thesis. The principle of collective security supplied the language and legitimacy of the response, but it was the end of the Cold War that supplied the means: only Soviet-American cooperation allowed the Security Council to act on principles that had been paralysed for forty years. The Cold War's end was the enabling condition; collective security was the framework it finally made operable.
  • Argument 1 - The Cold War's end as the enabling condition. Soviet acquiescence let Resolutions 660 to 678 pass at speed; Gorbachev's USSR voted with the US or abstained rather than shielding a client. Evidence: 678 passed 12-2 with China abstaining - unthinkable in the era of the superpower veto.
  • Argument 2 - Collective security as the framework. The response was built on UN Charter principles: condemnation of aggression (660), sanctions (661), non-recognition of annexation (662), and authorised force (678). Evidence: the 35-nation Coalition and Bush's "New World Order" rhetoric cast the war as collective enforcement, not a US war.
  • Argument 3 - The interaction and its limits. Collective security worked here because great-power interests aligned - oil, sovereignty and the post-Cold-War order all pointed the same way. The selectivity of the response (no comparable action elsewhere) suggests interest, not principle, did much of the work.
  • Historiography. Lawrence Freedman and Efraim Karsh (The Gulf Conflict, 1993) stress the diplomatic novelty of Soviet-American cooperation as the precondition for the UN's action. F. Gregory Gause III (2010) emphasises the regional and great-power interests beneath the collective-security language.
  • Judgement. Collective security framed and legitimised the response, but the end of the Cold War made it possible; where the two coincided the UN acted decisively. The enabling factor was the new superpower relationship, with collective security the principle it allowed to function.

MODEL PARAGRAPH (Argument 1)

The unprecedented unity of the Security Council in 1990 is unintelligible without the collapse of the Cold War order that had paralysed it since 1945. For four decades the superpower veto had made collective action against a client state almost impossible; in August 1990, by contrast, Mikhail Gorbachev's Soviet Union - long Iraq's principal arms supplier - chose cooperation over protection. Resolution 660 condemned the invasion within hours, and on 29 November Resolution 678 authorised "all necessary means" by twelve votes to two, with China abstaining rather than vetoing. As Lawrence Freedman and Efraim Karsh emphasise, this Soviet acquiescence was the diplomatic precondition for everything that followed: the same invasion a decade earlier would have produced a deadlocked Council and a divided world. The principle of collective security had existed in the Charter all along; what changed in 1990 was that the end of the Cold War finally allowed it to be exercised.

Marker's note. A band-6 response keeps "to what extent" in view (ranking the Cold War's end against collective security, not just describing the UN response), anchors each claim in dated evidence, sets at least two historians in genuine tension, and reaches a graded judgement. Listing the resolutions without weighing the two explanations caps the response in the middle bands.
