What was the U.S. military's response in Afghanistan after the 9/11 attacks called?

  1. Operation Just Cause

  2. Operation Enduring Freedom

  3. Operation Desert Shield

  4. Operation Urgent Fury

The correct answer is: Operation Enduring Freedom

The U.S. military's response in Afghanistan after the September 11, 2001 attacks was called Operation Enduring Freedom. This operation began on October 7, 2001, and was primarily aimed at dismantling al-Qaeda and removing the Taliban from power, as they had provided sanctuary to al-Qaeda operatives who orchestrated the attacks on the United States. The operation marked the beginning of a lengthy military engagement in Afghanistan that would evolve into a broader conflict against terrorism. Operation Enduring Freedom not only involved combat operations but also efforts to stabilize Afghanistan and support the establishment of a new government. The operation lasted until December 2014, transitioning into a training and support role for Afghan forces under the NATO-led mission known as Resolute Support. The other operations listed, such as Operation Just Cause, Operation Desert Shield, and Operation Urgent Fury, refer to different military actions undertaken by the U.S. under different circumstances and in different countries, thus highlighting the distinct nature of Operation Enduring Freedom in the context of U.S. military history.
