The term was coined by U.S ambassador in UK John Hay. Splendid part of that war that lasted two months was unity of American people where Northerners, Southerners, Blacks and Whites fought toghether side by side as one, it is symbolic end of distrusts that last even longer than reconstruction era. John Hay (the United States Ambassador to the United Kingdom), writing from London to his friend Theodore Roosevelt declared that from start to finish it had been "a splendid little war." Few Americans would disagree with that assessment of the Spanish American War. It was short, it accomplished its goals, and it established the United States as an international power.
