Final answer:
The US invasion of Afghanistan in 2001 aimed to find those responsible for the 9/11 attacks and dismantle the Taliban government and al-Qaeda training camps. It led to the collapse of the Taliban government and efforts to rebuild Afghanistan.
Step-by-step explanation:
The US invasion of Afghanistan in 2001 was initially motivated by a goal of finding those responsible for the 9/11 attacks in New York City, which were traced back to al-Qaeda and Osama bin Laden, who was residing in Afghanistan at the time. The invasion, known as Operation Enduring Freedom, aimed to remove the Taliban government from power and dismantle the al-Qaeda training camps.
Although bin Laden managed to escape, the invasion led to the collapse of the Taliban government and a temporary reduction in the terror caused by the Taliban. The US military also focused on rebuilding civil society and infrastructure in Afghanistan, as well as supporting the establishment of a democratically elected government.
