Final answer:
Two weeks after the 9/11 terror attacks, the CIA entered Afghanistan to prepare for a U.S. invasion that aimed to dismantle al-Qaeda and remove the Taliban from power. The activities in Afghanistan and Iraq marked significant events in the U.S. response to 9/11, with distinct objectives for each country's invasion.
Step-by-step explanation:
Two weeks after the 9/11 attacks, a CIA team entered Afghanistan to prepare for an invasion. This operation was part of the initial response to the September 11 attacks, which were traced back to al-Qaeda and its leader Osama bin Laden, who was in Afghanistan at the time. The United States' military action in Afghanistan, called Operation Enduring Freedom, aimed to remove the Taliban from power and dismantle al-Qaeda's training camps. Although bin Laden escaped, the effort significantly disrupted the Taliban's control. The stated reason for the U.S. invasion of Iraq in 2003 was related to the Bush administration's belief that Saddam Hussein was developing weapons of mass destruction that could be provided to terrorist groups like Al Qaeda.
