Answer:
the imperial motives of the United States were unjustified. I believe this for many reasons, here are a few.
The actions of the United States were unjust because the nation brought upon itself to intervene in international/other nations' affairs. At that time America also, apparently, thought of itself highly and as a better nation. I think that if one nation isn't having issues like a war or a world-threatening problem, then there is no reason to get involved. This was also because the United States government was trying to reach its' goal of earning money and establishing an empire.
Often when the United States was beginning to be very unjust was in the early 1800s. Cuba began rebelling several times against the Spanish in the 1800s but was overpowered each time, harm against the Cuban citizens horrified many Americans. "in 1898 Maine accidentally blew up killing 260 men, the Americans falsely accused the Spanish of blowing up Maine as an excuse to go to war with them." The last part in my opinion is incredibly wrong to do.
Those were a few reasons that I think made the United States unjustified. What do you think?
