He added that under the régime of President Zelaya republican institutions had ceased to exist in Nicaragua except in name, that public opinion and the press had been throttled, and that prison had been the reward of any tendency to real patriotism. The government of the United States was convinced, he said, "that the revolution represents the ideals and the will of a majority of the Nicaraguan people more faithfully than does the government of President Zelaya."[269]

This note caused the speedy downfall of Zelaya's government. He tried to perpetuate his party in power by resigning the presidency to Dr. Madriz, but President Taft refused to recognize the Madriz government, and a few months later it was overthrown and the revolutionary party came into power, first under the presidency of Estrada and then under that of Adolfo Diaz.

The revolution had paralyzed agriculture and commerce and thrown the country into financial chaos. In October, 1910, the United States government sent Thomas C. Dawson to Managua to investigate conditions and to straighten out the political and financial affairs of Nicaragua. While he was engaged in this task, Secretary Knox negotiated at Washington two treaties, one between the United States and Honduras, signed January 10, 1911, and a similar treaty between the United States and Nicaragua, signed June 6. These treaties were intended to place the two countries concerned under the financial supervision of the United States. They provided for the appointment in each case of a collector of customs approved by the President of the United States, and made the customs receipts responsible for loans to be advanced by American bankers. The collectorship of customs was immediately established in Nicaragua without waiting for the ratification of the treaty by the Senate, and through the efforts of the State Department American bankers made preliminary loans to the Nicaraguan government. When the Senate rejected the treaty, the bankers refused to make further loans, and the situation was almost as bad as ever. In October, 1911, General Mena, minister of war and head of a faction of his own, was elected by the Assembly president of the republic, but as this was contrary to an agreement which had been made with Dawson, it did not meet with the approval of the United States, and President Diaz removed Mena from office and forced him to flee from the capital. Shortly afterwards Mena was taken seriously ill, and the opposition to President Diaz fell again under the control of Zelaya's followers. As President Diaz was unable to guarantee protection to the life and property of foreigners, he asked the United States for assistance. In answer to this request American marines were landed at Corinto and assumed control of the national railway which connected that port with the capital and the principal cities. The American minister made a public announcement to the effect that the United States intended to keep open the routes of communication and to protect American life and property. This announcement was a great blow to the revolutionists. Some of their leaders surrendered voluntarily to the American marines, while others were attacked and forced to surrender positions along the railroad which they insisted upon holding. In these operations seven American marines lost their lives. Since 1912 a legation guard of one hundred marines has been maintained at the capital of Nicaragua and a warship has been stationed at Corinto.

After the revolutionary movement was thus overthrown, Secretary Knox negotiated a new treaty for the purpose of helping the Nicaraguan government out of the financial straits in which it found itself. Great Britain was threatening to force the payment of its claims and certain German interests, which were operating banana plantations in Costa Rica, were trying to secure from the Nicaraguan government a concession for the construction of a canal from the Great Lake to the Atlantic along the San Juan river. According to the terms of the Knox treaty the United States was to pay Nicaragua $3,000,000 in return for an exclusive right of way for a canal through her territory, a naval base on the Gulf of Fonseca, and the lease for ninety-nine years of the Great Corn and Little Corn Islands in the Caribbean. This treaty was submitted to the Senate February 26, 1913, but the close of the Taft administration was then at hand, and no action was taken.

The Wilson administration followed the same policy, however, and in July, 1913, Secretary Bryan submitted a third treaty with Nicaragua containing the provisions of the second Knox treaty and in addition certain provisions of the Platt Amendment which defines our protectorate over Cuba. This treaty aroused strong opposition in the other Central American States, and Costa Rica, Salvador, and Honduras filed formal protests with the United States government against its ratification on the ground that it would convert Nicaragua into a protectorate of the United States and thus defeat the long-cherished plan for a union of the Central American republics. They also claimed that the treaty infringed their own rights. In 1858 Costa Rica had been granted perpetual rights of free navigation in the lower part of the San Juan river, and Nicaragua had agreed to consult her before granting any concessions for the construction of an interoceanic canal. Salvador and Honduras objected to the establishment of a naval base in the Gulf of Fonseca in close proximity to their coasts. They also asserted proprietary rights in the Gulf of Fonseca, claiming that Salvador, Honduras, and Nicaragua, as successors of the old Central American Federation, exercised joint ownership over the gulf. Efforts were made by the United States to arrive at a settlement with Costa Rica and Salvador on the basis of a money payment, but without success. Moreover, the Senate of the United States objected to the protectorate feature of the treaty and refused to ratify it, but the negotiations were renewed, and on August 5, 1914, a new treaty, which omits the provisions of the Platt Amendment, was signed at Washington. This treaty, which was finally ratified by the Senate, February 18, 1916, grants to the United States in perpetuity the exclusive right to construct a canal by way of the San Juan river and Lake Nicaragua, and leases to the United States for ninety-nine years a naval base on the Gulf of Fonseca, and also the Great Corn and Little Corn Islands as coaling stations. The consideration for these favors was the sum of $3,000,000 to be expended, with the approval of the Secretary of State of the United States, in paying the public debt of Nicaragua, and for other purposes to be agreed on by the two contracting parties.

In consenting to the ratification of the treaty the Senate, in order to meet the objections raised by Costa Rica, Salvador, and Honduras, attached to their resolution of ratification the proviso "that nothing in said convention is intended to affect any existing right of any of the said states." This reservation did not satisfy Costa Rica and Salvador, who took their cases to the Central American Court of Justice, requesting that Nicaragua be enjoined from carrying out the provisions of the treaty. Nicaragua refused to be a party to the action, but the court nevertheless assumed jurisdiction. Its decision in the case of Costa Rica was announced September 30, 1916. It declared that Nicaragua had violated Costa Rica's rights, but, as the court had no jurisdiction over the United States, it declined to declare the treaty void. A similar decision in the case of Salvador was handed down on March 2, 1917.[270]

Neither Nicaragua nor the United States has paid any attention to the decision of the Central American Court of Justice, which was set up under such favorable auspices by the Washington conventions. As a matter of fact, the court had not fulfilled the expectations of those who had been interested in its establishment, but it was unfortunate that it should have received its coup de grâce from the United States. Furthermore, it has been charged that the State Department, under the Knox régime, exploited the situation in Central America for the benefit of American capitalists, and that the Wilson administration has for years maintained a minority party in power through the presence of a body of American marines at the capital and a warship at Corinto. On the other hand, it cannot be denied that as a result of American policy, Central America has been freer from wars and revolutions for a longer period than at any other time in its history. The better element of the population appears to be satisfied with the situation.[271]

The treaty with the negro republic of Haiti, ratified by the Senate February 28, 1916, carries the new Caribbean policies of the United States to the farthest limits short of actual annexation. Shortly before the outbreak of the European war, Haitian finances were in such bad shape as the result of internal disorders that there was grave danger of European intervention, and the United States was considering the question of acquiring supervision over the finances of the republic. In June, 1915, a crisis in the internal affairs of Haiti seemed imminent and, at the request of the State Department, Rear-Admiral Caperton was ordered to Haitian waters. Towards the latter part of July the government of President Guillaume was overthrown, and he and members of his cabinet took refuge in the French and Dominican legations. These buildings were entered by a mob, President Guillaume was slain at the gate of the French legation, his body cut in pieces, and dragged about the town. Admiral Caperton at once landed a force of marines at Port au Prince in order to protect the lives and property of foreigners. An additional force was brought from Guantanamo and the total number raised to two thousand and placed under the command of Colonel Waller. There was but slight resistance to the landing of the marines, but a few days later a conflict occurred in which two Americans were killed.[272] On August 12 a new president was elected who coöperated with the American forces in their efforts to establish peace and order, and on September 16 a treaty with the United States was signed at Port au Prince. This treaty provides for the establishment of a receivership of Haitian customs under the control of the United States similar in most respects to that established over the Dominican Republic. It also provides for the appointment, on the nomination of the President of the United States, of a financial adviser, who shall assist in the settlement of the foreign debt and direct expenditures of the surplus for the development of the agricultural, mineral, and commercial resources of the republic. It provides further for a native constabulary under American officers appointed by the President of Haiti upon nomination of the President of the United States. And it extends to Haiti the main provisions of the Platt Amendment. By controlling the internal financial administration of the government the United States hopes to remove all incentives for those revolutions which have in the past had for their object a raid on the public treasury, and by controlling the customs and maintaining order the United States hopes to avoid all possibility of foreign intervention. The treaty is to remain in force for a period of ten years and for another period of ten years if either party presents specific reasons for continuing it on the ground that its purpose has not been fully accomplished.

The latest acquisition of the United States in the Caribbean is that of the Danish West Indies, or Virgin Islands. Reference has already been made to the treaty negotiated by Secretary Seward in 1867 for the purchase of these islands, which was unfortunately rejected by the Senate. Another attempt at purchase was made by President Roosevelt in 1902. A treaty providing for the cession of the group to the United States was signed at Washington on January 24 of that year and approved by the Senate February 17, but this time the Danish Rigsdag refused to give its approval. President Roosevelt was moved by the consideration that the Danish Islands were of great strategic importance in connection with the problem of guarding the approaches to the Panama canal. The commercial value of the islands is also great. Moreover, the United States was confronted by the possibility of their falling under the control of Germany or some other European power, which might use them as a naval base. Had Germany been successful in the recent war, she might have forced Denmark to sell or cede the islands to her. In view of this possibility, negotiations were taken up again with Denmark in 1916, and on August 4 Secretary Lansing concluded a treaty by which the United States acquired the islands of St. Thomas, St. John, and St. Croix, together with some adjacent small islands and rocks, for the sum of $25,000,000. This treaty was duly ratified by the Senate and the ratifications were exchanged January 17, 1917.

The rapid advance of the United States in the Caribbean, described in the preceding pages, naturally aroused the fears of the smaller Latin-American states and lent color to the charge that the United States had converted the Monroe Doctrine from a policy of benevolent protection to one of imperialistic aggression. As a matter of fact, the Monroe Doctrine has never been regarded by the United States as in any sense a self-denying declaration. President Monroe said that we should consider any attempt on the part of the European powers "to extend their system to any portion of this hemisphere as dangerous to our peace and safety." The primary object of the policy outlined by President Monroe was, therefore, the peace and safety of the United States. The protection of Latin-American states against European intervention was merely a means of protecting ourselves. While the United States thus undertook to prevent the encroachment of European powers in Latin America, it has never admitted any limitation upon the possibility of its own expansion in this region. The silence of the Monroe Doctrine on this question has been remedied to some extent by President Wilson, who, at the outset of his administration, gave the assurance that "the United States will never again seek one additional foot of territory by conquest." This declaration, followed by his refusal to be forced into war with Mexico, has done much to remove the suspicion with which our recent policies in the Caribbean have been regarded by our Southern neighbors. His sincerity was further attested by his ready acceptance of the proffered mediation of the A B C powers in the Mexican embroglio and by the encouragement which he has given to the Pan American movement.
