Answer:
After reading about the United States and their imperial motives in the 1800s to the early 20th century, I believe that most of their actions were unjustified. Americans justified the imperialistic behavior by basically claiming it was their responsibility to intervene with other nation's affairs as a superior nation. However I think it isn't justifiable to intervene with other nation's affairs just because you may be a superior nation. The United States government never lost sight of their goal to earn money and establish an empire.
An example of American actions being unjustified would be in the late 1800s when Cuba began rebelling several times against the Spanish but were overpowered each time, atrocities against the Cuban citizens horrified many Americans. Then in 1898 the Maine accidentally blew up killing 260 men, the Americans falsely accused the Spanish of blowing up the Maine as an excuse to go to war with them. As a result 400 American lives were lost as well as another 2,000 from diseases such as yellow fever and malaria.
Another example of American actions being unjustified would also be in the late 1800s when the United States launched a surprise attack on the Spanish fleet in Manila bay Philippines destroying most of their ships then seizing the island of Luzon. The Filipinos began a fight for independence in 1899 leaving 4,000 Americans dead and 200,000 Filipinos dead. These are just some of my reasons that support why American Imperialism was unjustified.
