Review Questions

• How did the September 11 attacks change public perception of terrorism in the United States?
  • The September 11 attacks drastically changed public perception of terrorism in the United States, shifting it from a distant concern to a direct threat faced on American soil. Before these attacks, terrorism was often viewed as an issue affecting other countries; however, after witnessing such a devastating event, there was a growing awareness of vulnerabilities within U.S. borders. This heightened sense of insecurity led to increased fear and anxiety about future attacks and significantly influenced public support for government measures aimed at combating terrorism.
• In what ways did the War on Terror emerge as a response to the September 11 attacks, and what were its immediate implications?
  • The War on Terror emerged as a direct response to the September 11 attacks with a focus on combating terrorism globally. The U.S. quickly mobilized military forces to invade Afghanistan in October 2001 to target al-Qaeda operatives and dismantle their network. This military action marked a shift in U.S. foreign policy towards preemptive strikes against perceived threats, leading to long-term military engagements in multiple countries and significant changes in international relations as nations aligned or opposed U.S. actions based on their views on terrorism.
• Evaluate the effectiveness of post-9/11 counterterrorism strategies implemented by the U.S. government and their impact on civil liberties.
  • Post-9/11 counterterrorism strategies have had mixed effectiveness, achieving some successes in preventing further large-scale attacks while also drawing criticism for infringing on civil liberties. Measures such as increased surveillance, data collection, and laws like the USA PATRIOT Act have raised concerns about privacy rights and government overreach. While some argue these actions have enhanced national security by disrupting potential threats, others contend that they have eroded trust between citizens and government institutions, highlighting a complex balance between safety and individual freedoms that remains a contentious issue today.
