Is the United States Imperialistic?

Yes the United States is imperialistic.  One of the first examples of American imperialism was the annexation of Hawaii in 1898.  After several discussions over a treaty of annexation, Hawaii became a territory.  In the same year the USS Maine exploded.  The explosion forced the United States to fight in the Spanish-American War in which we gained the Philippines, Guam, Puerto Rico, and Cuba.  Winning this war put America ahead in the race for land.  Lastly, what makes the United States imperialistic are the vast number of military bases we have around the world.
