The 2003 Invasion of Iraq: A Detailed Overview of Operation Iraqi Freedom

The 2003 invasion of Iraq marked the initial and most decisive phase of the protracted Iraq War. Officially commencing on March 19, 2003, with an aerial assault, followed by ground operations on March 20, this invasion, formally known as Operation Iraqi Freedom by the United States, was a swift military campaign. It spanned just over one month, encompassing 26 days of major combat operations, and saw a formidable combined force of troops from the United States, the United Kingdom, Australia, and Poland enter Iraqi territory.

Commencement and Key Milestones of the Invasion

The swift advance of the Coalition forces was a hallmark of this invasion phase. Notably, merely 22 days after the initial incursions, the Iraqi capital city of Baghdad fell to Coalition forces on April 9, 2003. This pivotal moment followed the intense, six-day-long Battle of Baghdad, which effectively secured the heart of the Iraqi government.

The formal conclusion of this early, major combat stage of the war was declared on May 1, 2003, by U.S. President George W. Bush. From the deck of the aircraft carrier USS Abraham Lincoln, President Bush delivered his controversial "Mission Accomplished" speech, signifying what was then perceived as the end of significant armed resistance. Following this declaration, the Coalition Provisional Authority (CPA) was established. This interim governmental body served as the first in a series of transitional administrations, guiding Iraq towards the establishment of a sovereign government and ultimately leading to the country's first parliamentary election in January 2005. While major combat operations concluded relatively quickly, U.S. military forces maintained a presence in Iraq for a significantly longer period, with their eventual withdrawal occurring in 2011.

Coalition Forces and International Involvement

The initial invasion force, spearheaded by the United States, comprised approximately 160,000 troops deployed to Iraq between March 19 and May 1, 2003. The composition of this multinational force demonstrated a clear hierarchy of contributions:

• Approximately 73% of the total force, or 130,000 soldiers, were American troops.
• The United Kingdom contributed around 45,000 soldiers, accounting for approximately 25% of the invasion force.
• Australia provided about 2,000 soldiers, representing roughly 1% of the total.
• Poland deployed 194 soldiers, constituting approximately 0.1% of the initial force.

Beyond these primary contributors, some thirty-six other countries subsequently participated in the stabilization and reconstruction efforts in the aftermath of the invasion. Preparations for the ground invasion were extensive, with a significant buildup of U.S. forces, approximately 100,000 troops, assembled in neighboring Kuwait by February 18, 2003. Crucially, the Coalition forces also received tactical and logistical support from the Peshmerga, the well-established military forces of Iraqi Kurdistan, particularly in securing the northern regions of Iraq.

Rationale, Controversies, and International Opposition

The stated justifications for the 2003 invasion of Iraq, as articulated by U.S. President George W. Bush and UK Prime Minister Tony Blair, centered on three core objectives: "to disarm Iraq of weapons of mass destruction (WMD), to end Saddam Hussein's support for terrorism, and to free the Iraqi people." However, these claims were met with significant international skepticism, particularly given that a United Nations inspection team, UNMOVIC (United Nations Monitoring, Verification and Inspection Commission), had reported finding absolutely no evidence of existing WMDs in Iraq just prior to the invasion's commencement.

Alternative perspectives emphasize the profound impact of the September 11, 2001, terrorist attacks on U.S. strategic calculations, shifting foreign policy towards pre-emptive action and fostering the concept of a "freedom agenda" aimed at promoting democracy in the Middle East. According to Prime Minister Blair, the direct trigger for military action was Iraq's perceived failure to seize a "final opportunity" to disarm itself of alleged nuclear, chemical, and biological weapons, which U.S. and British officials characterized as an "immediate and intolerable threat to world peace."

Public opinion within the United States reflected a complex stance. A January 2003 CBS poll indicated that 64% of Americans approved of military action against Iraq. However, this support was nuanced: 63% concurrently desired President Bush to pursue a diplomatic resolution over war, and a significant 62% believed that military intervention would actually increase the threat of terrorism directed against the U.S.

Internationally, the invasion of Iraq faced strong opposition from several long-standing U.S. allies, including the governments of France, Canada, Germany, and New Zealand. Leaders from these nations vocally argued that there was insufficient evidence of weapons of mass destruction in Iraq and that an invasion was therefore unjustifiable, especially in light of UNMOVIC's detailed report on February 12, 2003, which found no active WMD programs. Post-invasion discoveries of approximately 5,000 chemical warheads, shells, or aviation bombs did occur during the Iraq War. However, these were identified as residual weapons, built and abandoned earlier in Saddam Hussein's rule before the 1991 Gulf War. Crucially, these findings did not support the primary rationale of the U.S. and UK governments for the 2003 invasion, which asserted an active WMD threat.

Global Anti-War Protests

The looming prospect of war galvanized massive global opposition. On February 15, 2003, just one month before the invasion, millions participated in worldwide protests against the Iraq War. A remarkable demonstration in Rome alone drew an estimated three million people, a gathering that the Guinness Book of Records recognized as the largest anti-war rally ever recorded. According to French academic Dominique Reynié, the period between January 3 and April 12, 2003, witnessed an astonishing 36 million people across the globe engaging in nearly 3,000 separate protests against the impending conflict.

Invasion Operations and Strategic Maneuvers

The military campaign itself was characterized by rapid advances and overwhelming air superiority. The invasion was immediately preceded by a targeted airstrike on the Presidential Palace in Baghdad on March 20, 2003, signaling the commencement of hostilities. The following day, Coalition ground forces launched their incursion into Basra Province from their staging points near the Iraqi-Kuwaiti border.

Simultaneously, special forces executed a complex amphibious assault from the Persian Gulf, successfully securing Basra and the surrounding vital petroleum fields. The main invasion army then pushed rapidly into southern Iraq, establishing control over the region and engaging in fierce combat, including the Battle of Nasiriyah on March 23. Extensive air strikes conducted across the entire country, coupled with precision attacks against Iraqi command-and-control centers, plunged the defending Iraqi army into disarray, effectively neutralizing any organized, coherent resistance.

Further north, on March 26, the 173rd Airborne Brigade executed a strategic airdrop near the city of Kirkuk. There, they linked up with Kurdish rebel forces, initiating several engagements against the Iraqi Army to secure the northern oil fields and territory, creating a formidable two-front advance.

The main body of Coalition forces continued their relentless drive towards the heart of Iraq, encountering remarkably little resistance. The majority of the Iraqi military was swiftly defeated, culminating in the occupation of Baghdad by Coalition forces on April 9. Subsequent operations targeted remaining pockets of Iraqi Army resistance, including the capture and occupation of Kirkuk on April 10, and the attack and capture of Tikrit on April 15. As Coalition forces solidified their control over the country, Iraqi President Saddam Hussein and his central leadership went into hiding. On May 1, President George W. Bush's declaration marked the formal end of the invasion period and the beginning of a prolonged phase of military occupation.

The Human Shield Movement

A unique civilian movement, known as the Human Shield Action to Iraq, emerged prior to and during the 2003 invasion. This group comprised individuals who traveled to Iraq with the deliberate intention of acting as human shields. Their objective was to physically interpose themselves at specific civilian infrastructure sites and public locations, aiming to deter U.S.-led Coalition forces from bombing these targets during the military campaign.
