What was the military operation launched against the Taliban in December 2001?

The correct choice is indeed Operation ENDURING FREEDOM. This operation was initiated in December 2001 following the events of September 11, 2001, and was designed as a military response to dismantle al-Qaeda and remove the Taliban regime in Afghanistan that was providing sanctuary to terrorist groups.

Operation ENDURING FREEDOM marked a significant moment in modern military history, representing the United States' commitment to combating terrorism on a global scale. The operation encompassed various military tactics and included cooperation with Afghan resistance groups, aiming to establish a more stable governance in Afghanistan.

In contrast, Operation IRAQI FREEDOM pertains to the military campaign that began in 2003 aimed at the overthrow of Saddam Hussein in Iraq. Operation NOBLE EAGLE refers to domestic security measures implemented in the United States following the 9/11 attacks, focusing on the protection of key infrastructure and forces within the homeland. Meanwhile, Operation DESERT STORM was the combat phase of the Gulf War in 1991, targeting Iraq following its invasion of Kuwait. All these operations, while significant in their contexts, are distinct from the mission objectives of Operation ENDURING FREEDOM.
