What argument was made by supporters of annexing territories like Hawaii and the Philippines?

Supporters of annexing territories such as Hawaii and the Philippines argued that it was essential to ensure that foreign nations did not seize these territories. This perspective was rooted in the geopolitical context of the late 19th and early 20th centuries, where there was a growing concern about imperial powers expanding their influence across the globe. By annexing these territories, the United States sought to secure strategic locations for military and naval bases while also establishing a foothold in important trade routes, particularly in the Pacific. The fear was that if the U.S. did not take control of these territories, rival nations—such as Japan or European powers—might do so, undermining American interests and security. This argument highlighted the belief in Manifest Destiny and the duty of the U.S. to expand its influence and protect against potential threats in a rapidly changing world.
