Answer:
Roosevelt believed in projecting American power. He sent the Great White Fleet on a worldwide tour to show off the modernized American navy and to state American interests in the Pacific. Roosevelt supported Panamanian independence in order to create the Panama canal. He signed the Roosevelt Corollary to the Monroe Doctrine which gave the United States the right to intervene in Latin America. Roosevelt also arbitrated in the Russo-Japanese War, an act which won a Nobel Peace Prize. At the onset of WWI, Roosevelt argued for immediate American intervention on the side of the Allies and even offered to lead a division of American soldiers in the conflict. Roosevelt believed that the United States had a duty to project power and its way of life abroad in order to cultivate both manly virtue at home and American values abroad.
On the continental expansion, Americans pushed Native Americans off their land making deals with them that favored the US more than the tribes. After that, Americans pushed their ideas to the areas being developed trying to make Native Americans abandon their own culture.
On the expansionism overseas the US returned the land to its original inhabitants, this happened in Cuba for example. This was the main difference between expansionism inside and outside the US.
The taking of Hawaii, Puerto Rico, and the Philippines was a violation of fundamental American ideals of self-government and democracy, this was actually the main argument of Anti-Imperialists. Once the US had claimed the territory they established their own rule and define role/impact in each respective country. Conquering other territories and forcing them to abide by American ideals and culture goes against the idea of American freedom.
