- Contributed to the outbreak of World War I: Isolationist policies prevented countries from intervening to prevent conflicts, leading to the buildup of tensions and rivalries that ultimately culminated in the war.
- Hindered international cooperation: Isolationist countries were reluctant to engage in collective security arrangements or alliances, making it difficult to address common threats and challenges.
- Limited economic development: Isolationist policies discouraged trade and investment between countries, hindering economic growth and prosperity.
Appeasement:
- Encouraged further aggression from Germany: Appeasement policies signaled to Germany that it could pursue its expansionist goals without facing serious consequences, emboldening it to take increasingly aggressive actions.
- Weakened the League of Nations: The failure of the League of Nations to take action against Germany's violations of the Treaty of Versailles undermined its credibility and effectiveness as an international peacekeeping organization.
- Led to the outbreak of World War II: Appeasement policies ultimately failed to prevent war and allowed Germany to gain significant territorial control in Europe, setting the stage for the outbreak of World War II.
