For the United States, the war with Afghanistan was one of the longest in its history, beginning on October 7, 2001 until December 28, 2014, with Operation Enduring Freedom. The United States blamed Afghanistan for protecting those responsible for the attacks of November 11, 2001. With the initial attack the Taliban came out of power, but then they recovered again.

Over the years, the war with Afghanistan became increasingly controversial as the United States struggled to achieve its goals of stabilizing the country, defeating terrorist groups, and promoting democracy. The war resulted in the deaths of thousands of American soldiers, Afghan civilians, and Taliban fighters, as well as billions of dollars in military and reconstruction costs.

Despite efforts to train and support the Afghan security forces, the Taliban continued to launch attacks and gain territory. The Afghan government remained weak and corrupt, unable to effectively govern the country or provide basic services to its citizens.

In 2014, the combat mission in Afghanistan officially ended, with the majority of US troops withdrawing from the country. However, a small number of troops remained to advise and assist Afghan forces in their ongoing fight against the Taliban and other militant groups.

The war in Afghanistan had a profound impact on the United States and Afghanistan, shaping foreign policy, military strategy, and public opinion for years to come. The legacy of the conflict continues to be felt today, as both countries grapple with the long-term consequences of their involvement in the war.
