Puerto Rico and the United States
Like Hawaii, the United States wanted to annex Puerto Rico. However, there were other reasons why America intervene in foreign affairs in Latin America. The U.S. wanted a chance to get rid of an European country such as Spain from the West Hemisphere. That was what the war between America and Spain was about when they were fighting over Cuba. The same instance is happening here since America is forbidding Spain to coming over because of the Monroe Doctrine in his hand. Also, it can relate the Blaine's "Big Sister Policy" Since America is standing up for the little country of Puerto Rico.
