Proponents of annexation argued that it was morally justified on several grounds:
* Economic benefits: The annexation of Hawaii would bring economic benefits to the United States, such as increased trade and the development of naval bases.
* National security: Hawaii's strategic location in the Pacific made it valuable as a naval base, which would increase the United States' military power and protect its interests in the region.
* Humanitarian concerns: Some argued that annexation would help improve the lives of the native Hawaiian population, bringing them education, healthcare, and other benefits of American civilization.
Opponents of annexation argued that it was morally unjustified on several grounds:
* Violation of Hawaiian sovereignty: The Hawaiian monarchy was overthrown by American forces in 1893, and the annexation was seen as a further violation of Hawaiian independence.
* Indigenous rights: The annexation ignored the rights of the native Hawaiian people, who were not given a say in the matter and whose culture and way of life were threatened by annexation.
* Economic exploitation: Some argued that the annexation was driven by economic interests, rather than genuine concern for the well-being of the Hawaiian people.
Ultimately, the moral justification of the annexation of Hawaii is a matter of perspective and historical interpretation. There are valid arguments to be made on both sides of the issue.
