Answer 2

In 19th century, Spanish fleet blew the American ship "the Maine" in Cuba, a Spanish colony. It angered the Americans and the American congress declared war against Spain.

Emilio Aguinaldo, the first Philippine president, who was in exile in Hong Kong, met the Americans and plotted to overthrow the Spanish rule in the Philippines.

The combined Filipino-American troops defeated the Spaniards. After that, the true dark colors of America was shown when she invaded Manila and closed it from the Filipinos.

To recognize defeat, the Spaniards signed a treaty with the Americans to purchase the Philippines, Guam, Mariannas, Carolines, etc. to America in exchange with $250,000.00. The treaty was called "The Treaty of Paris". The newly-established Philippine government appealed to the American congress, but the appeal was denied. Then the Philippine-American war started.

So it means that Guam, the Marianas, and the Carolines should be a territory of the Philippines since it was included in the ecclessiastical colonial government of Spain in the Philippines, united politically....

The Phillipines was transferred to the US, along with Puerto Rico and Guam by the Treaty of Paris that ended the Spanish-American war.
