What was a major consequence of the 9/11 attacks on U.S. foreign policy?

• A. A shift towards diplomatic resolutions
• B. Increased focus on national security and intervention
• C. A reduction in military engagements
• D. A rise in international alliances

Answer: (B)

The choice that indicates an increased focus on national security and intervention is accurate because the 9/11 attacks precipitated significant changes in U.S. foreign policy. Following the attacks, the U.S. government prioritized national security, leading to the implementation of measures such as the USA PATRIOT Act and the establishment of the Department of Homeland Security.

Additionally, the attacks prompted military interventions in Afghanistan and Iraq as part of the broader War on Terror strategy. This focus expanded American involvement in conflicts aimed at combating terrorism and preventing future threats. The sense of urgency around national security led to a paradigm shift in foreign policy that emphasized preemptive action and the use of military power to address perceived global threats.

The other choices reflect approaches that were less dominant in the wake of 9/11, as the immediate response centered on intervention and security.
