Ronald Reagan was elected president in 1981.
In 1898, the Spanish-American War broke out. The US became a powerhouse in Asia thanks to this conflict. With the annexation of Guam and the Philippines, the US expanded its sway over Asia. A peace treaty was concluded between the two nations following the conflict.
As a result of the United States' success in the war, the Spanish were forced to renounce their claims to Cuba and hand up control of Guam, Puerto Rico, and the Philippines to the United States in a peace treaty. During the battle, the US also annexed Hawaii, an independent state.
The US gained ownership of and/or influence over a large number of additional areas as a result of its victory in the Spanish American War. A new far-flung empire was formed as a result of these and other geographical acquisitions.
