During the 20th century, political figures such as Woodrow Wilson and Winston Churchill used the term "new world order" to refer to a new period of history characterised by a dramatic change in world political thought and in the global balance of power after World War I and World War II.[10] The interwar and post-World War II period were seen as opportunities to implement idealistic proposals for global governance by collective efforts to address worldwide problems that go beyond the capacity of individual nation-states to resolve, while nevertheless respecting the right of nations to self-determination.
