How Many Countries Has the US Bombed Since 9/11?
News Desk
Washington: Since the terrorist attacks of September 11, 2001, the United States has engaged in a global military campaign it dubbed the “war on terror,” launching large-scale invasions, air campaigns and counterterrorism operations that have reshaped US foreign policy for more than two decades.
According to research by the Costs of War project at Brown University and investigative reporting by multiple outlets, US military action after 9/11 has resulted in substantial human and economic costs.
Independent analyses estimate that US forces have directly caused around 940,000 deaths across conflict zones, with the toll significantly higher when indirect effects such as disease, disruption of health services, hunger and displacement are considered.
The United States has carried out air and ground strikes in at least 10 countries since 2001, including Afghanistan, Iraq, Yemen, Pakistan, Somalia, Libya, Syria, Venezuela, Nigeria and Iran, spanning conventional wars, drone campaigns and targeted strikes.
Major Conflicts and Casualties
The US invasion began in October 2001, marking America’s longest war. Direct violence in the Afghanistan and Pakistan region has been linked to tens of thousands of deaths, with broader impacts on civilian infrastructure and health.
Iraq: In March 2003, the US launched a full-scale invasion of Iraq based on claims of weapons of mass destruction that were never substantiated. Tens of thousands of Iraqi civilians and combatants were killed in the ensuing conflict.
US airstrikes against the Islamic State (ISIS) and other targets have been part of the broader Syrian civil war since 2014, contributing to significant fatalities.
Yemen: US support for the Saudi-led campaign against the Houthi movement has overlapped with counterterrorism operations, contributing to a high death toll and severe humanitarian crisis.
Across these and other theaters, direct deaths due to violent conflict are estimated at close to 940,000, while broader war-related impacts, such as disease, malnutrition, and collapse of public services, are estimated to push the total toll to at least 4.5 million deaths or more.
Economic Costs
The financial burden on the United States has been immense. Direct military and counterterrorism spending since 2001 is estimated at roughly $5.8 trillion, with additional obligations, particularly for veterans’ care and disability benefits, expected to add another $2.2 trillion or more over coming decades.
This brings the combined cost to taxpayers to around $8 trillion or higher.
Despite repeated presidential pledges to reduce America’s involvement in costly overseas wars, US military engagement continues in various forms under successive administrations.
Critics argue that these efforts have entrenched long-term instability in affected regions while exacting significant human and financial costs.
