• How did NATO's formation alter the landscape of military alliances in Europe after World War II?
  • The formation of NATO marked a significant shift in military alliances by establishing a formal and cooperative defense pact among Western nations. This alliance aimed to deter Soviet expansionism by presenting a united front, thus reshaping international relations and security dynamics.

• Discuss the implications of NATO's collective defense principle during the Cold War and its effects on U.S.-Soviet relations.
  • NATO's collective defense principle heightened tensions between the U.S. and the Soviet Union, as it solidified a clear division between Eastern and Western blocs. The promise that an attack on one member would be met with a unified response meant that both superpowers were compelled to build up their military capabilities and prepare for potential conflicts. This escalation contributed to an arms race and defined U.S.-Soviet relations throughout much of the Cold War period.
