Conflicts

The 2026 Israel-United States strike on Iran was the joint offensive that began on February 28, 2026, when Israeli and U.S. forces attacked Iranian military, regime, and nuclear-linked targets. The operation turned long-running confrontation over Iran's regional posture and nuclear program into direct interstate war involving major retaliatory strikes across the Middle East. The conflict combined preventive-war logic, alliance warfare, missile retaliation, energy-route risk, and the problem of escalation once a shadow conflict becomes open combat.

On 3 January 2026, the United States launched Operation Absolute Resolve, a military intervention in Venezuela that captured President Nicolas Maduro and his wife Cilia Flores after years of escalating confrontation between Washington and Caracas. U.S. forces struck air-defense targets across northern Venezuela and deployed operators into Caracas to seize Maduro, who was later transported to New York to face narcoterrorism charges. The operation also triggered an immediate leadership vacuum, with Vice President Delcy Rodriguez moving into the acting presidency amid claims of casualties among Venezuelan, Cuban, and U.S. personnel. The intervention brought years of sanctions, diplomatic breakdown, narco-trafficking accusations, regime-change pressure, and hemispheric power politics into open military intervention. It links coercive regime removal, oil politics, Latin American intervention history, and the recurring problem that external military success in decapitating a regime does not by itself answer who will govern the state that remains.

The Israel-Hamas War began on 7 October 2023, when Hamas and associated Palestinian armed groups launched a large surprise attack from Gaza into southern Israel, killing approximately 1,200 people, mostly civilians, and taking around 250 hostages. It was the deadliest day for Jews since the Holocaust. Israel declared war and responded with a major air, ground, and naval campaign aimed at destroying Hamas's military and governing capacity and recovering hostages, with the IDF advancing systematically through northern, central, and southern Gaza and causing massive destruction of infrastructure. The war became one of the most consequential conflicts of the 2020s because it combined massacre, hostage-taking, urban warfare, humanitarian collapse, mass displacement, regional escalation, U.S. policy pressure, and legal proceedings at the International Court of Justice. Gaza Health Ministry figures for October 2023 to January 2025 put Palestinian deaths at over 46,000, alongside widespread famine, the displacement of nearly the entire population of 2.3 million, and the destruction of hospitals, schools, and residential areas. Israel faced international criticism and an ICJ genocide case filed by South Africa. The conflict also expanded regionally, with Hezbollah opening a second front from Lebanon, Houthi attacks in the Red Sea, and Iranian missile strikes on Israel, while hostage negotiations remained a central issue throughout.

The Russo-Ukrainian War's full-scale phase began on 24 February 2022, when Russia launched a multi-axis invasion of Ukraine after eight years of conflict following the annexation of Crimea and war in Donbas. It is the largest war in Europe since World War II and a central test case for modern conventional warfare, drones, air defense, sanctions, mobilization, and alliance support. The conflict cannot be reduced to a single battlefield narrative. It includes a failed Russian attempt to seize Kyiv, long attritional fighting in the east and south, missile and drone attacks on civilian infrastructure, Ukrainian long-range strike adaptation, Russian mobilization and fortification, Western military assistance, and continuous information warfare.

Operation Protective Edge was the major 2014 Gaza war between Israel and Hamas-led armed groups, unfolding after worsening tensions in Jerusalem and the West Bank, renewed rocket fire, and the entrenched political divide between Gaza and the Palestinian Authority. The campaign combined Israeli air strikes and a ground incursion with rocket attacks from Gaza, tunnel warfare, and severe civilian harm in a dense urban battlespace. The conflict demonstrated adaptations in the Gaza arena after earlier wars, including the use of tunnel networks, increased international attention to civilian impact, and the ongoing failure of military escalation to achieve a stable political outcome.

The Ukrainian Crisis, also known as the Russo-Ukrainian War, was the political-security breakdown that began in February 2014 following the Euromaidan revolution, or Revolution of Dignity, and the collapse of Viktor Yanukovych's rule. Russia seized and annexed Crimea and supported paramilitaries in the Donbas against Ukraine's military, ending the post-Cold War assumption that Europe's borders were largely settled and creating the conflict architecture that later widened into full-scale war. That escalation came in February 2022, when Russia launched a full-scale invasion of Ukraine, the largest conflict in Europe since the Second World War. It has produced a severe humanitarian and refugee crisis, with millions requiring aid and hundreds of thousands of deaths, and has disrupted global food supplies through blockades of Ukrainian ports. The crisis linked regime change, covert and overt military coercion, territorial seizure, proxy warfare, sanctions, and the long transition from political crisis into interstate and hybrid conflict.

Operation Pillar of Defense was an eight-day Israeli military operation in Gaza in November 2012, launched after escalating rocket fire and Israeli-Palestinian violence and ending with an Egyptian-brokered ceasefire. The operation linked short-duration air power, missile defense, civilian exposure, and ceasefire brokerage in one compressed episode. It also connected airstrikes, rocket warfare, Iron Dome interceptions, urban civilian risk, Hamas-Israel escalation dynamics, the politics of ceasefire mediation, and the difficulty of assessing proportionality in dense conflict zones. It became a template for later arguments about deterrence, proportionality, and the limits of punitive escalation.

Operation Cast Lead was the major Israeli military campaign in Gaza from late 2008 into early 2009, launched after years of blockade, rocket fire, failed truce arrangements, and deepening fragmentation in the wider Israeli-Palestinian conflict. It combined intensive air strikes, a ground operation, Hamas and other armed-group rocket attacks, and a major humanitarian crisis in a densely populated battlespace. It showed how the Gaza arena evolved into recurring, bounded wars shaped by blockade, urban warfare, international scrutiny, and the gap between tactical military operations and durable political settlement.

The War in South Ossetia in 2008 was the short but strategically consequential conflict in which Georgian forces, South Ossetian separatists, and Russian troops fought in and around South Ossetia before the war widened into broader Russian military operations in Georgia. Though brief, it changed regional security assumptions and deepened the fragmentation of Georgian sovereignty. The conflict links separatist confrontation, interstate escalation, civilian harm, deterrence failure, and the post-Soviet pattern of unresolved territorial disputes becoming wider wars. It also stands as an early warning case for how Moscow could turn a frozen dispute into a fast regional shock. Its longer significance lies in how clearly it exposed the gap between political signaling and operational readiness. Georgia sought to change a deteriorating local balance, but Russia entered the crisis with escalatory dominance, prepared formations, and a broader strategic willingness to expand the theater. The war demonstrates how frozen conflicts can become testing grounds for regional power projection, beyond its narrative as a five-day conflict.

The Iraq War began with the U.S.-led invasion of Iraq on March 20, 2003, based on claims of weapons of mass destruction, later unsubstantiated, and alleged links to terrorism. Coalition forces toppled Saddam Hussein's regime in three weeks, but the prolonged occupation faced a devastating insurgency involving Sunni militants, Shia militias, al-Qaeda in Iraq, and later the Islamic State, which developed into sectarian conflict and state-building failure. Key events include the Battle of Fallujah (2004), the Abu Ghraib scandal, the Golden Mosque bombing of 2006 that sparked sectarian civil war, the counterinsurgency troop surge of 2007, and the gradual U.S. withdrawal completed in December 2011. Estimates of Iraqi deaths range from about 150,000 to more than 600,000, alongside 4,497 U.S. military deaths and over 3 million displaced Iraqis. The consequences continued through Iraqi politics, militia power, the regional destabilization that created conditions for the rise of ISIS, and U.S.-Iran competition.

The War in Afghanistan from 2001 to 2021 began after the September 11 attacks, when the United States and allies intervened to remove the Taliban government and target al-Qaeda. It became a long counterinsurgency, state-building, NATO, reconstruction, and counterterrorism campaign that ended with Taliban victory and the collapse of the Afghan republic. The conflict is associated with special operations, air power, counterinsurgency, NATO coalition warfare, drones, Afghan security forces, corruption, civilian harm, reconstruction failure, and the limits of external state-building.

The Kargil War was a 1999 India-Pakistan conflict in the Kargil sector of Kashmir, fought after Pakistani forces and irregulars occupied positions on the Indian side of the Line of Control. The conflict involved high-altitude warfare, nuclear-era escalation control, air power constraints, mountain logistics, international diplomacy, and the wider India-Pakistan rivalry. It was a limited war under a nuclear shadow. The fighting stayed geographically constrained, but the political stakes were larger because both states had recently demonstrated nuclear capability and international actors were watching for escalation. The Kargil War illustrates how a local tactical intrusion can escalate into a strategic crisis when the surrounding security environment is unstable.

The Eritrean-Ethiopian War from 1998 to 2000 was a major interstate conflict between two former liberation allies whose post-independence relationship broke down into a destructive border war. Although the dispute is often summarized through Badme, the fighting widened beyond that point and became one of the largest conventional conflicts in Africa during its period, with trench warfare, mass mobilization, and deep political consequences on both sides. The conflict linked post-liberation state rivalry, border demarcation, ceasefire monitoring, conventional military escalation, and the long afterlife of unresolved mistrust in the Horn of Africa. It was not merely a technical border dispute but also a struggle over sovereignty, prestige, and the unfinished political meaning of independence after shared revolutionary victory.

The First Congo War of 1996 to 1997 was the conflict in which Laurent-Désiré Kabila's anti-Mobutu coalition, the Alliance of Democratic Forces for the Liberation of Congo-Zaire (AFDL), advanced across Zaire and brought down Mobutu Sese Seko's 32-year dictatorship, opening a new and far more volatile phase in Central African warfare. The war was triggered by ethnic tensions in eastern Zaire, particularly involving Rwandan Hutu refugees and Tutsi populations after the 1994 Rwandan genocide. Rwanda and Uganda provided crucial military support to Kabila's forces, viewing the campaign as necessary to eliminate Hutu militia bases threatening their borders. Mobutu's army, weakened by years of corruption and neglect, offered limited resistance as the AFDL advanced across the vast country, capturing Goma, Kisangani, and ultimately Kinshasa. International involvement was limited, with most powers abandoning Mobutu. Approximately 200,000 to 300,000 people died, many from disease and hunger. The war ended with Mobutu's exile and Kabila's assumption of the presidency, and the country was renamed the Democratic Republic of Congo. It linked refugee militarization after Rwanda, cross-border intervention, regime decay, alliance warfare, and state collapse under conditions that immediately fed wider regional conflict.

The Croatian War of Independence, fought from 1991 to 1995 during the breakup of Yugoslavia, set Croatian state forces against the Yugoslav People's Army (JNA) and Croatian Serb paramilitaries, later organized as the self-declared Republic of Serbian Krajina. It combined secession, state formation, ethnic displacement, UN peacekeeping, and major offensives that reshaped the political map of the western Balkans. The war followed Croatia's declaration of independence in June 1991, opposed by Serb minority populations and the Belgrade-controlled JNA. Major battles included the siege of Dubrovnik and the fighting for Osijek, Vukovar, and Zadar, and the conflict featured ethnic cleansing, mass displacement, and the destruction of cultural heritage. Croatian forces, initially outgunned, gradually built capability through arms imports and foreign assistance. The war moved through an initial JNA offensive in 1991, a period of stabilization from 1992 to 1994, and Croatian offensives in 1995 in Operation Flash and Operation Storm; Operation Storm recovered the occupied territories but caused a mass exodus of Croatian Serbs. International involvement included UN peacekeeping through UNPROFOR, arms embargoes, and diplomatic mediation. Approximately 20,000 people died and 500,000 were displaced. The fighting ended with the Erdut Agreement, which completed the reintegration of Croatian territory and established Croatia as an independent state. The conflict links the collapse of a federal state, militia and regular-force interaction, international diplomacy, and postwar accountability in one of the key wars of the Yugoslav dissolution.

The Gulf War, also known as Operation Desert Storm, was the 1990-1991 international conflict triggered by Iraq's invasion and annexation of Kuwait on August 2, 1990 and ended by a U.S.-led coalition of 35 nations operating under United Nations authority. Its phases ran from the political crisis and the defensive buildup in Saudi Arabia through the aerial bombing campaign that began on January 17, 1991, a 100-hour ground offensive, and the liberation of Kuwait. The war demonstrated the effectiveness of precision airpower, including precision-guided munitions, stealth aircraft such as the F-117, GPS-guided warfare, and real-time satellite intelligence, alongside armored maneuver. Iraqi forces suffered devastating losses, including the destruction of much of their armor along the Highway of Death. Approximately 25,000 to 50,000 Iraqi military personnel, 1,000 Kuwaiti civilians, and 292 coalition military personnel died. The conflict linked post-Cold War collective security, coalition warfare, oil politics, and Arab-state diplomacy. Kuwait was liberated but Saddam Hussein remained in power, leaving an unresolved aftermath inside Iraq and the wider Gulf and beginning the long containment of Iraq.

The Nagorno-Karabakh War of 1988 to 1994 was the late Soviet and post-Soviet conflict between Armenians and Azerbaijanis over Nagorno-Karabakh, a predominantly Armenian-populated enclave within Azerbaijan, and the territories surrounding it. It combined nationalism, state collapse, irregular and conventional fighting, mass displacement, atrocities, and outside mediation. The war grew out of ethnic tensions and demands by Karabakh Armenians for unification with Armenia, escalating from protests to armed conflict as the Soviet Union collapsed. Major episodes included the siege of Stepanakert, the capture of Shusha, and fighting around the Lachin corridor. Armenian forces, drawing on both Karabakh Armenians and support from Armenia proper as well as aid from the diaspora, proved militarily effective, while Azerbaijani forces, despite numerical superiority, struggled with internal political instability and poor military coordination. The fighting involved conventional warfare, artillery bombardment, and the targeting of civilians, and atrocities included the Khojaly massacre and other episodes of ethnic cleansing. International involvement included Russian mediation and arms supplies to various sides. Approximately 30,000 people died and more than 1 million were displaced. Armenian military victory left Armenian control of Nagorno-Karabakh and seven surrounding districts under an unresolved ceasefire order that shaped the South Caucasus for decades, connecting post-Soviet state formation, ethnic security, refugees, ceasefire lines, and OSCE diplomacy to the renewed fighting of 2020 and the 2023 Azerbaijani takeover.

The Falklands War was the ten-week undeclared conflict of April to June 1982 between Argentina and the United Kingdom over the Falkland Islands, known in Argentina as the Malvinas, together with South Georgia and the South Sandwich Islands. Argentina invaded on April 2, 1982, and Britain dispatched a naval task force of over 100 ships across 8,000 miles. The short South Atlantic war combined sovereignty claims, naval expeditionary operations, air-sea combat, alliance diplomacy, and a land campaign. Key events include the sinking of the ARA General Belgrano by HMS Conqueror, the only nuclear submarine kill in history, the Exocet missile attack on HMS Sheffield, the Battle of Goose Green, and the final assault on Port Stanley, with Britain recapturing the islands by June 14. The fighting demonstrated the vulnerability of surface ships to anti-ship missiles and the importance of air superiority. A total of 649 Argentine and 255 British military personnel died, plus three Falkland islanders. The war linked local island sovereignty to national prestige and democratic legitimacy on both sides, with postwar effects in London, Buenos Aires, where defeat contributed to the fall of the military junta, and the wider South Atlantic.

The Iran-Iraq War was an eight-year interstate war fought from 1980 to 1988, beginning when Iraq under Saddam Hussein invaded Iran on 22 September 1980 amid revolutionary upheaval, border disputes, and regional power competition. It became one of the longest and bloodiest conventional conflicts of the twentieth century, devolving into trench warfare reminiscent of the First World War, with human wave attacks, missile strikes on cities in the War of the Cities, extensive Iraqi use of chemical weapons including against Kurdish civilians at Halabja, and the tanker war in the Persian Gulf. Key battles included Khorramshahr, the Fao Peninsula operations, and Operation Badr. An estimated 500,000 to 1,000,000 soldiers and civilians died on both sides. The fighting ended in a UN-brokered ceasefire under Resolution 598, with no territorial changes but deep strategic consequences. It shaped the Islamic Republic's security state, Iraq under Saddam Hussein, Gulf militarization, U.S. regional policy, and later Middle Eastern conflict patterns.

The Sino-Vietnamese War was China's 1979 punitive invasion of northern Vietnam after Vietnam's intervention in Cambodia, Hanoi's alignment with the Soviet Union, and worsening border and ethnic tensions between Beijing and Hanoi. The campaign was brief but intense, with Chinese forces attacking across multiple border axes before withdrawing after announcing that punitive aims had been achieved. It was a short war with disproportionately large strategic consequences. The war mattered far beyond its short duration. It changed how China, Vietnam, Cambodia, and the Soviet Union interpreted regional security, and it left a frontier politics problem that outlasted the battlefield phase. The war linked post-Vietnam War Indochina, the fall of the Khmer Rouge, Sino-Soviet rivalry, border warfare, military reform lessons, and the long shadow of China-Vietnam strategic mistrust. It was not a peripheral border clash, but a compact war embedded in the larger Cold War geometry of Asia.
