‘Everything changed’: The human cost of 25 years of US wars

Twenty-five years have passed since 19 al-Qaeda hijackers seized four commercial aeroplanes and slammed into the World Trade Center and the Pentagon, killing nearly 3,000 people.

What followed was a series of US-led wars that reshaped Washington’s foreign policy for a generation, in which every year since 2001, US forces have bombed a country somewhere in the world, devastating the lives of millions.

“Everything changed,” Omar*, an Iraqi student at the time of the 2003 invasion of Iraq, told Al Jazeera, recalling how the war was fought on the false pretence that the country harboured weapons of mass destruction.

Less than a month after 9/11, the US invaded Afghanistan, launching what President George W Bush called the “War on Terror” - a series of seemingly endless wars and military campaigns spanning Afghanistan, Iraq and countries across the Middle East, South Asia and Africa.

According to the Cost of War project at Brown University’s Watson Institute for International and Public Affairs estimates that US-led wars since 2001 have directly or indirectly killed an estimated 4.5 to 4.7 million people - including approximately 940,000 direct deaths and 3.6 to 3.8 million indirect deaths from disease, malnutrition and health complications.

On October 7, 2001, the US launched Operation Enduring Freedom. The Taliban fell within weeks, but the war went on to span nearly 20 years across four US presidents - the longest conflict in US history.

An estimated 176,000 people died as a direct result of the war , according to an analysis from the Costs of War project, while hunger, disease and untreated injuries killed hundreds of thousands more.

Food insecurity rose from 62 percent of Afghans before the war to 92 percent after it, and unexploded ordnance and landmines continue to kill and maim civilians.
