Drone Warfare

How unmanned aerial vehicles transformed counterterrorism — and raised profound legal and ethical questions.

The Drone Revolution

Armed drones went from experimental technology to the centerpiece of US counterterrorism under the Obama administration. The logic was appealing: eliminate high-value targets with precision strikes, no boots on the ground, no American casualties, and far cheaper than conventional military operations.

The CIA and US military conducted thousands of drone strikes in Pakistan, Yemen, Somalia, Libya, and across the Sahel. The Bureau of Investigative Journalism estimates that US drones killed between 10,000 and 17,000 people from 2002 to 2020. High-profile kills included al-Qaeda leaders Anwar al-Awlaki (a US citizen, killed in Yemen in 2011), and Ayman al-Zawahiri (killed in Kabul in 2022).

But the precision narrative was contested. Independent investigations found significant civilian casualties. A leaked 2015 Pentagon study revealed that during one five-month period in Afghanistan, nearly 90% of those killed in drone strikes were not the intended targets.
