The question of why is there war in Iraq cannot be answered with a single event or individual. It is a layered historical puzzle composed of colonial-era decisions, geopolitical struggles, and domestic ambitions that converged into decades of instability. Understanding this requires looking beyond immediate triggers to the structural forces that have shaped the modern Iraqi state.
The Colonial Inheritance and Artificial Borders
To understand the roots of conflict, one must first look to the aftermath of World War I. The Sykes-Picot Agreement carved up the Ottoman Empire, drawing lines across the Middle East that paid little heed to ethnic, tribal, or religious realities. Britain, seeking to secure its imperial routes, established a mandate over Mesopotamia, creating the modern state of Iraq by forcibly merging three distinct Ottoman vilayets: Baghdad, Basra, and Mosul. This artificial construct placed Sunni Arabs in the center, Shia Arabs in the south, and Kurds in the north, setting the stage for internal friction that persists to this day.
The Rise of Authoritarianism and Repression
Following independence, Iraq oscillated between monarchy and military dictatorship, but it was the secular Ba'ath Party coup of 1968 that centralized power brutally. Under Saddam Hussein, the state relied on a pervasive security apparatus to suppress dissent, particularly among the Kurdish population in the north and the Shia majority in the south. The use of chemical weapons against Kurdish villages in the 1980s and the violent suppression of Shia uprisings after the Gulf War created deep-seated grievances that fragmented national identity and made the state itself a source of danger for its own people.
Regional Power Struggles
Iraq has always been a focal point in the regional contest between Sunni and Shia powers. Neighboring Iran, with its Shia theocracy, viewed Saddam’s secular regime as a direct ideological threat, leading to the devastating eight-year war in the 1980s that solidified animosities. Later, the US invasion dismantled the Sunni-dominated power structure, inadvertently empowering the Shia majority and aligning Iraq more closely with Tehran. This realignment fueled a cold war dynamic in the region, where external actors often prioritized their own interests over Iraqi stability, perpetuating cycles of violence.
The 2003 US Invasion and Its Fallout
The most direct catalyst for the intense war following 2003 was the US-led invasion based on the premise of weapons of mass destruction. The decision to disband the Iraqi military and de-Ba'athify the state institutions created a power vacuum and instantly alienated the Sunni minority, who had previously held all the power. This security vacuum allowed extremist groups, including al-Qaeda in Iraq, to flourish. The insurgency that followed targeted both the occupying forces and the new Shia-led government, leading to the sectarian civil war that defined the mid-2000s.
Economic Interests and Resource Control
While often overshadowed by security narratives, control over oil resources has been a consistent undercurrent in Iraq's conflicts. The wealth generated by oil has been a primary prize for competing factions, both internal and external. Disputes over oil revenue sharing between Baghdad and regional governments, combined with the lucrative nature of the energy sector, have incentivized armed groups to maintain a state of conflict to fund their operations and influence. The struggle over who controls the tap that funds the state has been a persistent driver of tension.
The legacy of these intertwined factors—colonial borders, authoritarian repression, regional interference, and the chaos of intervention—means that peace in Iraq remains fragile. The war against the Islamic State, while militarily successful, left new militias powerful and the central government struggling to reassert authority. Consequently, the answer to why is there war in Iraq points to a continuous struggle over the nature of the state itself, the distribution of power among its factions, and the ongoing influence of external forces that see Iraq as a critical piece on a much larger geopolitical chessboard.
