What kind of lasting effects did the Spanish-American War have on the United States?
Weegy: The formal peace negotiations took place in Paris, beginning on Oct. 1, 1898. The American representatives had committed themselves to an expansive imperialistic policy for the United States. [ Spain granted Cuba its independence, and the United States was given Puerto Rico and Guam. The difficult issue was the Philippines. McKinley was undecided on what to do about the 7,000-island former Spanish colony. Soon, however, he was caught up in the fervor of imperialism that was sweeping the United States. He finally concluded that "the march of events rules and overrules human action." The Philippines would be annexed, and- in the words of New York Tribune editor Whitelaw Reid- the Philippines would "convert the Pacific Ocean into an American lake." Spain parted with the Philippines in exchange for a payment of 20 million dollars from the United States. In so doing Spain lost the last remnants of its world empire and for the first time in centuries it could concentrate on internal problems and development. The United States, in contrast, gained an empire. The flush of victory was soon dissipated, however, and the nation became fiercely divided over the matter of imperialism. To keep the Philippines the United States fought a bloody three-year guerrilla war. The United States found itself doing in the Philippines precisely what it had condemned Spain for doing in Cuba. In moving forcefully into the Pacific, the United States soon found itself in competition with the rising power of Japan. As early as the presidency of Theodore Roosevelt, the groundwork had already been laid for conflict with Japan in World War II. The Spanish-American War assured that the Panama Canal would be built (since the United States now needed a two-ocean navy) and thus that commerce would flow to both the Atlantic and Pacific oceans. The war also advanced the career of the assistant secretary of the Navy, Theodore Roosevelt, who won the vice-presidency in 1900 and became president in ... (More)
