Answer:
United States
Step-by-step explanation:
The United States was the country that won control of Guam and the Philippine islands as a result of a war. The United States captured Guam during the Spanish-American War on June 21, 1898. Moreover, this was officially ceded by Spain to the United States on December 10, 1898. The Philippines was also ceded to the United States according to the Treaty of Paris. However, the Filipino nationalists objected to this, which led to the Philippine-American War.
