Which policy exemplifies the U.S. commitment to interventionism during the age of imperialism?

The Open Door Policy is a significant example of the U.S. commitment to interventionism during the age of imperialism because it aimed to ensure equal trading rights for all nations in China and was intended to prevent any one power from monopolizing trade in that region. This policy emerged in the late 19th century when various imperial powers, including Britain, France, Germany, and Japan, were vying for influence over China. By advocating for an Open Door Policy, the United States sought to protect its commercial interests and assert its presence in international trade despite not having territorial possessions in China.

The Open Door Policy reflects interventionism as it involved the U.S. actively shaping foreign relations and economic policies in a way that favored American interests. This approach underscored the broader imperialistic mindset of the time, where the U.S. aimed to expand its influence and access to markets, even in regions where it did not have direct colonial control.
