Following the September 11, 2001, terrorist attacks, the United States rapidly expanded its use of unmanned aerial vehicles (UAVs) as a central component of its military strategy in the War on Terror.12

The U.S. military integrated platforms such as the General Atomics MQ-1 Predator and the MQ-9 Reaper to conduct both persistent surveillance and lethal strike missions. These systems allowed for dynamic targeting and flexible engagement in regions including Afghanistan, Pakistan, Yemen, and Somalia. A fatal attack in Kandahar on October 7, 2001, is often cited as the first instance of a U.S. drone strike, marking a significant shift toward the use of uncrewed systems for combat operations.312

While drones provided tactical advantages, their use has raised profound ethical and legal concerns regarding sovereignty, civilian casualties, and the psychological impact on populations under constant surveillance. It is a fundamental ethical imperative that military operations, including those involving advanced technology, must adhere to international humanitarian law to protect human life and dignity.1
