The Republic of Ecuador and the United States of America maintained close ties based on mutual interests in maintaining democratic institutions; combating cannabis and cocaine; building trade, investment, and financial ties; cooperating in fostering Ecuador's economic development; and participating in inter-American organizations.
 Ties are further strengthened by the presence of an estimated 150,000-200,000 Ecuadorians living in the United States and by 24,000 U.S. citizens visiting Ecuador annually, and by approximately 15,000 U.S. citizens residing in Ecuador.
 The United States assists Ecuador's economic development directly through the Agency for International Development (USAID) program in Ecuador and through multilateral organizations such as the Inter-American Development Bank and the World Bank.
 In addition, the U.S. Peace Corps operates a sizable program in Ecuador.
 More than 100 U.S. companies are doing business in Ecuador.
The Inter-American Peace Force (IAPF) was established, by the Organization of American States, on 23 May 1965, after the United States's intervention in the Dominican Republic.
 It largely consisted of over 42,600 United States military personnel, plus the following troops were sent by each country;
The Haitian Revolution provoked mixed reactions in the United States.
 In June 1793 when the Haitian people, led by Toussaint Louverture, overthrew the French colonial rule and declared themselves an independent colony, it made the neighboring United States uneasy.
 The slaves in Saint-Domingue’s were able to observe the growing disunity among the white colonists and themselves.
 They realized that they would need to seek an opportunity to stop the tyranny that was being placed upon them, thus they took a stand and revolted.
 The Haitian Revolution of 1804 impacted the United States of America, led by Thomas Jefferson, instilling fear of racial instability in the US, and the possible problematic effect the revolution could have on the early foreign relations and trade between the US and the new independent Haiti.
 Thomas Jefferson realized that the Haitian Revolution had the potential to cause an upheaval against slavery in the US not only by the slaves themselves, but by white abolitionists as well.
 Southern slaveholders feared that the revolt might spread from the island of Hispaniola to the slave plantations of the Southern United States.
 The primary goal of the US was to maintain social order in the country, so the United States attempted to suppress the Haitian Revolution.
 The US even went as far as to refuse acknowledgement of Haitian independence until 1862, which was during the heat of the North American civil war; coincidentally the main causal factor for the war between the states was slavery.
 The second major impact that the Haitian Revolution had on the United States was on early foreign relations and trade that had been conducted with Haiti.
 The United States had conducted trade and commerce with the Haitian island under French rule during the eighteenth century.
 Haiti was the main producer of the United States supply of sugar and coffee, and once the Haitian slave population had broken from slavery, the US was reluctant to continue trade with them in fear that they would upset the French and the Southern slaveholders.
 American merchants conducted a substantial trade with the plantations on Hispaniola (aka the French colony of Saint Domingue or Haiti).
 But there were anti-slavery advocates in northern cities who believed that consistency with the principles of the American Revolution — life, liberty and equality for all—demanded that the U.S. support the slave insurgents.
 An extremely beneficial aspect and real estate triumph that resulted from the Haitian Revolution and impacted the United States was the Louisiana Purchase.
 Once Napoleon had lost his control of the land holding in the Caribbean to the Haitian rebellion, he felt that the French territory in the southern part of the United States was useless to the French Empire.
 The US was only interested in the New Orleans area; however, the revolution enabled the sale of the entire territory west of the Mississippi River for around $15 million.
 This purchase more than doubled the United States’ territory.
USS "Phelps" (DD-360) was a World War II-era "Porter"-class destroyer in the service of the United States Navy.
 She was named for Thomas Stowell Phelps, who was a Rear Admiral in the US Navy in 1884.
 "Phelps" was laid down 2 January 1934 by Bethlehem Shipbuilding Corporation's Fore River Shipyard, Quincy, Massachusetts; launched 18 July 1935; sponsored by Mrs. Richard A. Kearny; and commissioned 26 February 1936, Commander Albert H. Rooks in command.
 In November 1936 "Phelps", along with the cruiser "Chester", escorted the heavy cruiser "Indianapolis" carrying President Franklin D. Roosevelt to Buenos Aires, Argentina for the opening of the Inter-American Peace Conference of 1936.
 The cruise included good-will visits to Montevideo, Uruguay and Rio de Janeiro, Brazil.
The illegal drug trade in Haiti involves trans-shipment of cocaine and marijuana to the United States.
 It is a major shipment route.
 The island of Hispaniola, which Haiti shares with the Dominican Republic places Haiti in an ideal location for drug smuggling between Colombia and Puerto Rico.
 Because Puerto Rico is a Commonwealth of the United States, shipments are generally not subject to further U.S. Customs inspection after reaching the territory.
 Cocaine is also often smuggled directly to Miami in freighters.

 General Finch had a career of "firsts" including the US Army's first night landing with a single, five-million-candlepower floodlight in 1927.
 He also established and endowed the General John P. McConnell Award at the United States Air Force Academy.
 Considered by many as the father of the strong, independent Air National Guard existing today, General Finch retired in 1957.
 No man has had greater impact on the Air Force Reserve and National Guard than has General George G. Finch.A graduate of the University of Georgia and a member of the Georgia Bar, General Finch was enshrined in the Georgia Aviation Hall of Fame May 18, 1996.
