1) The Platt Amendment declared Cuba a U.S. protectorate.
U.S. involvement in Cuba resulted from the U.S. defeat of Spain in the Spanish-American War of 1898. Cuba had to meet a series of conditions in order for U.S. troops to withdraw from Cuba.
2) Monroe Doctrine declared that an act by a European power in the Western Hemisphere would be considered a threat.
Proposed by Monroe in 1823? (check me on this) from lessons learned after the War of 1812 and continued British meddling in North America.
3) Roosevelt's Corollary set up the United States as a Latin American police force.
This was Roosevelt's famous "Speak Softly and Carry a Big Stick" policy. The world tour of the U.S. Navy's Great White Fleet is also a good example of the Roosevelt Corollary. U.S. troops were sent to various Latin American countries in the early 20th century (Nicaragua, Dominican Republic, Haiti, etc.) when U.S. business interests were threatened.
4) Panama Canal reduced time and expense of U.S. global trade by shortening shipping route between the Atlantic and the Pacific.
One of the most important engineering feats of the 20th century.
Answer:
D. Rapid modernization and the formation of a strong military made Japan very powerful
Explanation:
The Meiji restoration was crucial for Japan and its development. Instead of being colonized like most of the Asian countries, Japan became the invader. The Meiji restoration brought in big changes in Japan, quickly industrializing the nation, making it economically strong, and creating a modern and very powerful army. All this made the colonial powers think twice before they try anything with Japan, so they tried to avoid any conflict with it. In fact, Japan became so strong, that in the years to come it managed to defeat Russia and China on its own, and started to colonize parts of Asia afterwards.
