On September 11, 2001 Terrorists, from the group al-Qaeda attacked the world trade centers, the pentagon, but failed to attack a fourth target in Washington D.C. These attacks shocked and angered people all over the world. The United States responded by declaring a war on terror and invading Afghanistan, where many believed that Osama Bin Laden, the leader of al-Qaeda, was hiding.
Also in Afghanistan was the Taliban, a group that was harboring al-Qaeda. The operation in Afghanistan is called Operation Enduring Freedom. This was different from many wars in that the U.S and coalition forces were fighting an insurgent enemy, and not a standing army.
The majority of the fighting has been guerrilla warfare. The first major attacks of the war were the bombing of Kabul and other major cities in Afghanistan. One of the first major operations was in Tora Bora. Osama Bin Laden was thought to be hiding in the Tora Bora Mountains. The mountains were bombed, but unfortunately because of a lack of ground forces, Osama was able to escape. By the 12th of November, the Taliban forces fled Kabul. Later the U.S. put Hamid Karzai in power as the interim president of Afghanistan. Though there were many other battles with insurgents.
The U.S. focused its efforts on the invasion of Iraq in March of 2003. The war in Afghanistan is still going on today.
