Final answer:
The U.S. invasion of Afghanistan aimed to dismantle al-Qaeda, capture Osama bin Laden, and remove the Taliban from power, marking the beginning of the U.S. war on terror and the effort to rebuild and stabilize Afghanistan.
Step-by-step explanation:
U.S. Invasion of Afghanistan Goal
After the September 11, 2001 attacks, Operation Enduring Freedom was the United States' military response to dismantle al-Qaeda's presence in Afghanistan and remove the Taliban from power.
The primary goal of the U.S. invasion of Afghanistan was to find those responsible for the attacks, notably Osama bin Laden and other al-Qaeda members, while overthrowing the Taliban regime that harbored them.
These actions symbolized the start of the U.S. war on terror and aimed at rebuilding Afghan society, supporting the establishment of a democratically elected government, and ensuring the prevention of future terrorist training camps within the country.
The U.S. subsequently supported the new government led by Afghan President Hamid Karzai, and continued to combat Taliban insurgency, despite facing complications with military resources being redirected to the invasion of Iraq in 2003.
