What this topic is asking
The contemporary era was reshaped by a single morning of terror. The TEKS want you to explain the September 11, 2001 attacks, the war on terror (including the wars in Afghanistan and Iraq), and the renewed tension between national security and civil liberties. This is a Reporting Category 1 (History) topic with a strong Government and Citizenship dimension.
The attacks
The war on terror
In response to the attacks, the United States:
- invaded Afghanistan (2001), whose Taliban government sheltered al-Qaeda and its leader, Osama bin Laden;
- invaded Iraq (2003), in a controversial war justified at the time by claims about weapons of mass destruction;
- waged a long, costly struggle against terrorism that defined US foreign policy for years.
Security at home
The attacks reshaped domestic policy as well. The government created the Department of Homeland Security to coordinate protection against terrorism, dramatically increased airport and border security, and expanded surveillance and law-enforcement powers, notably through the USA PATRIOT Act.

A single-select item (Reporting Category 1, History).
Correct answer: launch the war on terror, including military action in Afghanistan against the groups responsible.
Markers reward connecting 9/11 to the US response of a war on terror and the invasion of Afghanistan (which sheltered al-Qaeda). Distractors connecting 9/11 to the start of the Cold War or to the Great Depression are wrong by decades.

A two-part evidence-based item (Reporting Category 3, Government and Citizenship).
Part A (1 point): a domestic response such as creating the Department of Homeland Security, increasing airport and border security, or expanding surveillance and law-enforcement powers (for example under the USA PATRIOT Act).
Part B (1 point): explain the debate that these measures, meant to improve national security, also raised concerns that expanded surveillance and detention powers could threaten Americans' privacy and civil liberties, echoing earlier wartime tensions.
Markers reward a real domestic security response and a clear explanation of the security-versus-liberty debate it produced.
