Review Questions

• How does ANZUS reflect the geopolitical landscape of the post-World War II era, particularly concerning Cold War dynamics?
  • ANZUS was established during a time of heightened tensions stemming from the Cold War, where the threat of communism was a major concern for Western allies. The treaty created a framework for collective defense among Australia, New Zealand, and the United States, illustrating their shared commitment to counteract Soviet influence in the Asia-Pacific region. This collaboration not only solidified military ties but also reinforced the idea that regional security depended on strong alliances among democratic nations.
• In what ways has New Zealand's nuclear policy affected its relationship with the ANZUS alliance since the 1980s?
  • New Zealand's anti-nuclear stance in the 1980s led to significant tension within the ANZUS framework, resulting in the U.S. suspending its treaty obligations toward New Zealand in 1986. This move highlighted a divergence in defense policies among the signatories, as Australia maintained its commitment while New Zealand opted for nuclear-free policies. As a consequence, New Zealand's exclusion from certain defense discussions has impacted both nations' strategic collaboration within ANZUS.
