Final answer:
The U.S.'s acquisition of the Philippines was influenced by strategic military considerations, economic interests, and an imperialistic ideology, with the aim to secure trade routes, harness resources, and prevent other powers from gaining a foothold in the Pacific.
Step-by-step explanation:
The U.S.'s motive for purchasing the Philippines from Spain was driven by several factors, including strategic military goals, economic aspirations, and an imperialistic ideology. The strategic military value of the islands was significant since they provided a gateway to important Asian markets and a position of strength in the Pacific region. Furthermore, the United States aimed to tap into the economic potential of the Philippines through trade with China and access to the islands' raw materials.
There were also ideological motivations, such as the belief in American exceptionalism and a sense of duty to govern and 'uplift' populations that were deemed incapable of self-rule. Prominent figures like President William McKinley and Senator Albert J. Beveridge supported this view, which intertwined with the broader trend of empire-building among Western powers.
Moreover, there was the pragmatic concern of preventing other nations, like Germany or Japan, from establishing their influence in the region. Ultimately, the acquisition reflected both imperialistic ambitions and geopolitical strategy of the United States at the turn of the 20th century.
