History of the United States (1991–2008) significant person Osama bin Laden
Early Islamist terrorist attacks
The 1990s also featured a series of increasingly violent attacks associated with Islamist terrorists, including al-Qaeda, a radical Islamist militant organization led by Osama bin Laden. On February 26, 1993, a truck bomb was detonated at the World Trade Center in New York City, killing six civilians and injuring 919 others, 88 firefighters, and 35 police officers. The attack was intended to destroy the foundation of the North Tower, knocking the tower into the South Tower, which would destroy both buildings and kill thousands of people. While this did not happen, the bomb caused considerable damage to the lower levels of the North Tower. In 1994, four men were convicted of carrying out the bombing and in 1997, two men were convicted for their roles, including the truck driver and the mastermind, Ramzi Yousef.On June 25, 1996, members of Hezbollah Al-Hejaz bombed the Khobar Towers, a complex in Khobar, Saudi Arabia, where members of the United States Air Force were being housed, killing 19 American airmen and injuring over 300 other people.On August 7, 1998, Al-Qaeda bombed the U.S. embassies in Kenya and Tanzania, killing 224 people, including 12 Americans. The U.S. launched cruise missile strikes on a terrorist training camp in Afghanistan, yet this failed to destroy al-Qaeda's vast network.
On October 12, 2000, al-Qaeda militants bombed the USS Cole off the coast of Yemen, killing 17 U.S. sailors and severely damaging the ship.War in Afghanistan
After the 9/11 attacks, Congress passed the Authorization for Use of Military Force Against Terrorists, authorizing the President "all necessary and appropriate force against the nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001." This act resulted in the 2001 invasion of Afghanistan, in President George W. Bush's broader Global War on Terrorism. The objective of the 2001 invasion, known as Operation Enduring Freedom, was to remove the Islamic fundamentalist Taliban lead government from power in Afghanistan, and to capture top level al-Qaeda leaders, including its founder Osama bin Laden. The invasion, fought in conjunction with the U.S.'s NATO allies, began on October 7, 2001, quickly leading to the overthrow of the Taliban government and implementation of Hamid Karzai as Afghanistan's interim president. In early 2002, after the Battle of Tora Bora and success with Operation Anaconda, the United States began focusing on military intervention in Iraq, shifting military and intelligence resources away from Afghanistan in War on Terror, with U.S. Secretary of Defense Donald Rumsfeld stating in May 2003 that the "major combat" in the conflict was over. With the approval of the new Afghan Constitution by the Loya jirga and election of President Karzai in 2004, Afghanistan later held its first parliamentary elections in over 30 years in 2005.
With a total of 22,000 U.S. troops deployed in Afghanistan by May 2006, the U.S. joined in the ISAF lead Operation Mountain Thrust. In the attempt to quell the Taliban insurgency in southern Afghanistan, more than 1,000 insurgents and 150 ISAF troops were killed in the two-month operation, being the bloodiest period since the start of the war in 2001. With ISAF assuming complete command of security forces in Afghanistan in October 2006, the U.S. saw mounting skepticism from European allies over the war at the 2006 Riga summit. U.S.-Afghan diplomatic relations began to flare after the August 2008 Azizabad airstrike in Herat Province, which killed 91 civilians, including 60 children and 15 women. The attack sparked protest over "collateral damage"; with a 40% increase in civilian deaths in 2008.
