The Gulf War, the War on Terror, and the conflicts in Afghanistan and Iraq shaped the first decade of the twenty-first century and continue to influence global politics today. This final lesson evaluates the lasting legacy of these conflicts, drawing together the key themes of the course.
The conflicts covered in this course caused immense human suffering.
| Conflict | Military Deaths | Civilian Deaths | Refugees/Displaced |
|---|---|---|---|
| Gulf War (1991) | ~292 coalition; ~20,000–35,000 Iraqi | ~2,000–3,000 | ~1.5 million Kurds |
| Afghanistan (2001–2014) | ~3,500 coalition (inc. 2,400 US, 456 UK) | ~26,000+ | ~2.6 million |
| Iraq War (2003–2011) | ~4,800 coalition (inc. 4,500 US, 179 UK) | Estimated 100,000–600,000+ (figures highly disputed) | ~4.7 million displaced |
Exam Tip: Civilian casualty figures for the Iraq War are highly contested. The Iraq Body Count project documented over 100,000 deaths from violence, while a controversial Lancet study estimated over 600,000 excess deaths. Be prepared to acknowledge this uncertainty in exam answers.

The overthrow of Saddam Hussein did not bring the stability that had been promised. Instead, Iraq experienced years of insurgency, sectarian violence, and political instability.
| Legacy | Detail |
|---|---|
| Sectarian divisions | The conflict deepened the Sunni-Shia divide; political power shifted to the Shia majority |
| ISIS / Daesh | The instability created by the war contributed to the rise of Islamic State (ISIS) in 2013–2014, which seized large parts of Iraq and Syria |
| Regional instability | The war destabilised the wider Middle East; Iran's influence in Iraq grew significantly |
| Democracy | Iraq held elections but democratic institutions remained weak and corruption was rampant |
| Oil | Iraq's oil production eventually recovered and exceeded pre-war levels, but the wealth was unevenly distributed |
| Refugees | Millions of Iraqis were displaced; many never returned home |
| Veterans | Iraqi veterans and civilians suffer from PTSD, injuries, and the effects of depleted uranium |
Key Term: ISIS (Islamic State of Iraq and Syria) — also known as ISIL or Daesh. A jihadist group that emerged from the remnants of al-Qaeda in Iraq. By 2014, it had seized territory across Iraq and Syria and declared a "caliphate." The group's rise was directly connected to the power vacuum created by the Iraq War.
The conflict in Afghanistan became the longest war in American history. Despite enormous investment, the outcome was deeply uncertain.
| Legacy | Detail |
|---|---|
| Taliban survival | Despite twenty years of war, the Taliban were never defeated |
| Women's rights | Significant progress was made (education, employment, political participation), but these gains were fragile |
| Opium production | Afghanistan remained the world's largest opium producer throughout the conflict |
| Corruption | The Afghan government was plagued by corruption; billions of dollars in aid were wasted |
| Pakistan | The Taliban's sanctuary in Pakistan was never eliminated; US-Pakistan relations remained strained |
| Cost | The USA spent over $2 trillion on the Afghanistan War |
| US withdrawal | US combat operations officially ended in December 2014 (though a residual force remained) |
| Impact | Detail |
|---|---|
| US credibility | The failure to find WMD in Iraq and the prolonged conflicts damaged US credibility worldwide |
| Transatlantic relations | The Iraq War strained relations between the USA and European allies (particularly France and Germany) |
| UN authority | The decision to invade Iraq without explicit UN authorisation weakened the UN system |
| Rise of China and Russia | While the USA was preoccupied with the Middle East, China and Russia expanded their influence |
| International law | The doctrine of pre-emptive war set a controversial precedent |
| Coalition fatigue | NATO allies became increasingly reluctant to commit troops to foreign interventions |
| Impact | Detail |
|---|---|
| Political divisions | The wars deepened partisan divisions; support for intervention declined |
| Veterans | Over 50,000 US soldiers wounded; high rates of PTSD, suicide, and homelessness among veterans |
| War Powers debate | Renewed debate about the President's authority to commit troops without Congressional approval |
| Financial cost | Combined cost of Iraq and Afghanistan estimated at $4–6 trillion (including long-term veterans' care) |
| Obama elected | Barack Obama's opposition to the Iraq War was a key factor in his 2008 election victory |
| Impact | Detail |
|---|---|
| Tony Blair's legacy | Blair's support for the Iraq War defined and damaged his political legacy |
| Chilcot Inquiry (2016) | A 7-year inquiry concluded that the UK's decision to go to war was based on "flawed intelligence" and that planning for the aftermath was "wholly inadequate" |
| Trust in government | Public trust in politicians declined — particularly regarding intelligence and decisions to go to war |
| Military covenant | Greater public awareness of the duty owed to military personnel and veterans |
Key Term: Chilcot Inquiry — the official UK inquiry into the Iraq War, chaired by Sir John Chilcot. Published in July 2016 after seven years of work, it concluded that the war was not a "last resort," that intelligence was presented with "a certainty that was not justified," and that planning for the aftermath was "wholly inadequate."
| Lesson | Explanation |
|---|---|
| Intelligence must be reliable | The WMD failure showed the catastrophic consequences of acting on flawed intelligence |
| Post-war planning is essential | The chaos in Iraq demonstrated the importance of planning for what comes after military victory |
| Nation-building is difficult | Afghanistan showed that creating stable institutions in a country with deep ethnic divisions, corruption, and hostile neighbours is enormously challenging |
| Military power has limits | The world's most powerful military could not decisively defeat insurgencies in Iraq or Afghanistan |
| Unintended consequences | Military intervention can destabilise regions, create power vacuums, and produce threats worse than those it aimed to address (e.g., ISIS) |
| Public support matters | Democratic governments cannot sustain wars that their populations oppose |
| International legitimacy matters | Acting without clear UN authority undermines international law and reduces allied support |
| Interpretation | Argument |
|---|---|
| Interventionist | The wars were necessary responses to genuine threats (WMD, terrorism); they removed brutal regimes and advanced democracy |
| Anti-interventionist | The wars were based on flawed intelligence (or deception), violated international law, caused enormous suffering, and destabilised the region |
| Realist | The wars reflected a misunderstanding of the limits of military power; diplomacy, containment, and deterrence would have been more effective |
Exam Tip: For the highest marks in extended-writing questions, show awareness of different perspectives on the conflicts. You might write: "Those who supported the wars argue they removed dangerous regimes and demonstrated resolve against terrorism. Critics counter that the wars were based on flawed intelligence, caused disproportionate civilian suffering, and destabilised the Middle East, ultimately creating new threats like ISIS."
