What were the three major goals of American foreign policy in the last half of the nineteenth century?

In the last half of the nineteenth century, American foreign policy aimed to expand territorial influence through westward expansion and the acquisition of new lands, exemplified by events like the annexation of Hawaii and the purchase of Alaska. A second goal was to promote American trade and economic interests, particularly in Asia, leading to initiatives like the Open Door Policy in China. Lastly, there was a desire to assert the United States as a global power, which involved increasing military presence and engaging in conflicts that positioned the nation favorably on the world stage.
