Answer:
Assuming we mean Jose Marti...
Marti's known opinions and principles suggest that he would have been opposed to the concept of American expansionism and imperialism.
Marti was a staunch supporter of Cuban independence and self-determination, and he felt that all nations should have the right to rule themselves free of external intervention. He was also a supporter of democracy and human rights, claiming that imperialism and colonialism were inherently incompatible with these ideals.
Considering these sentiments, Marti is likely to have resisted any US efforts to govern the Hawaiian islands or preserve its influence in Samoa. He may have also been sceptical of the notion of constructing the Nicaragua canal if it was viewed as a tool of increasing US influence or control over other nations.
Finally, Marti regarded Cuban independence as part of a larger battle for freedom and democracy throughout the Americas. He thought that all nations should be free to pursue their own destinies without outside influence or dominance. As such, he would almost certainly have been critical of any US acts that he perceived as violating these ideals.
