Review Questions

• How did the Korean War demonstrate the broader geopolitical tensions of the Cold War?

This conflict became a flashpoint for Cold War dynamics, reflecting how regional disputes were influenced by global power struggles. The war also set a precedent for U.S. military intervention in other conflicts seen as threats to democracy worldwide.

  • NSC-68 called for a substantial increase in military spending and a more aggressive stance against communism globally. This document significantly influenced U.S. foreign policy decisions leading up to and during the Korean War, as it justified military action to contain communist expansion. The belief that a failure to intervene in Korea could embolden communist movements elsewhere prompted the U.S. to take decisive action when North Korea invaded South Korea.

The stark differences in political ideologies and economic systems have contributed to ongoing tensions and periodic conflicts between the two Koreas, maintaining their division into distinct entities even decades after the war.
