International tensions refer to the strained relationships and conflicts between countries or groups of nations, often arising from unresolved disputes, differing national interests, or historical grievances.

Review Questions

  • How did the Treaty of Versailles contribute to international tensions in the years following World War I?
    • The Treaty of Versailles imposed harsh reparations on Germany and redrew borders in Europe, causing widespread resentment among Germans and leading to a sense of injustice. This created fertile ground for extremist political movements and heightened nationalistic sentiments. As a result, the economic and social turmoil within Germany contributed to international tensions by fostering hostility towards other nations that supported the treaty.
  • Evaluate the effectiveness of the League of Nations in mitigating international tensions after World War I.
    • The League of Nations was intended to promote peace and resolve disputes through diplomacy. However, it struggled with enforcement due to a lack of military power and the absence of key nations like the United States. This inability to address conflicts effectively, such as the invasions by Japan in Manchuria and Italy in Ethiopia, illustrated its weaknesses, resulting in increased international tensions as aggressor nations acted without fear of repercussions.
  • Analyze how nationalism played a role in escalating international tensions during the interwar period.
    • Nationalism intensified rivalries between nations as groups sought self-determination and control over disputed territories. The formation of new states from former empires often led to ethnic conflicts and border disputes. This competitive nationalism fostered an environment where countries were less willing to compromise or collaborate internationally. As national pride became intertwined with militarism, many nations pursued aggressive policies that ultimately escalated tensions into open conflict.
