Review Questions

• How does John Mearsheimer's concept of offensive realism differ from traditional liberal perspectives in international relations?
  • Mearsheimer's concept of offensive realism differs from traditional liberal perspectives by emphasizing that states are inherently aggressive and driven by a desire for power rather than cooperation. While liberals believe that states can achieve lasting peace through institutions and interdependence, Mearsheimer argues that the anarchic nature of the international system compels states to prioritize their survival through power maximization. This leads to inevitable competition and conflict, challenging the optimistic views held by liberal theorists.
• What implications do Mearsheimer’s theories have on U.S. foreign policy, particularly in relation to great powers like China and Russia?
  • Mearsheimer’s theories suggest that U.S. foreign policy should focus on countering the rising power of adversaries like China and Russia to maintain global dominance. His perspective implies that the U.S. must adopt a more confrontational stance rather than seeking cooperative relationships, as rising powers will always seek to challenge established ones. This has led to debates on whether the U.S. should pursue strategies aimed at balancing against these powers or if it should engage in a more isolationist approach to avoid conflict.
• Evaluate Mearsheimer’s argument about preventive wars in the context of international relations theories and provide examples from history.
  • Mearsheimer’s argument about preventive wars highlights the aggressive nature of state behavior when a rival appears to be gaining power. This idea resonates with historical examples such as the U.S. invasion of Iraq in 2003, justified by the belief that Saddam Hussein posed a future threat due to his potential acquisition of weapons of mass destruction. By evaluating this argument through different international relations theories, it contrasts sharply with liberal perspectives advocating for diplomacy and conflict resolution, revealing the persistent tension between realism’s focus on power dynamics and liberalism’s emphasis on cooperation.
