the event, all natives, citizens, denizens, or subjects of the hostile nation or government, being males of the, age of fourteen years and upwards, who shall be within the United States, and not actually naturalized, shall be liable to be apprehended, restrained, secured, and removed, as alien enemies. The President is authorized, in any such event, by his proclamation thereof, or other public act, to direct the conduct to be observed, on the part of the United States, toward the aliens who become so liable; the manner and degree of the restraint to which they shall be subject, and in what cases, and upon what security their residence shell be permitted, and to provide for the removal of those who, not being permitted to reside within the United States, refuse or neglect to depart therefrom; and to establish any other regulations which are found necessary in the premises and for the public safety;

WHEREAS, by Sections four thousand and sixty-eight, four thousand and sixty-nine, and four thousand and seventy, of the Revised Statutes, further provision is made relative to alien enemies,

NOW, THEREFORE, I, Woodrow Wilson, President of the United States of America; do hereby proclaim to all whom it may concern that a state of war exists between the United States and the Imperial German Government; and I do specially direct all officers, civil or military, of the United States that they exercise vigilance and zeal in the discharge of the duties incident to such a state of war and I do, moreover, earnestly appeal to all American citizens that they, in loyal devotion to their country, dedicated from its foundation to the principles of liberty and justice, uphold the laws of the land, and give undivided and willing support to those measures which may be adopted by the constitutional authorities in prosecuting the war to a successful issue and in obtaining a secure and just peace;

And, acting under and by virtue of the authority vested in me by the Constitution of the United States and the said sections of the Revised Statutes, I do hereby further proclaim and direct that the conduct to be observed on the part of the United States towards all natives, citizens, denizens, or subjects of Germany, being males of the age of fourteen years and upwards, who shall be within the United States and not actually naturalized, who for the purpose of this proclamation and under such sections of the Revised Statutes are termed alien enemies, shall be as follows:

All alien enemies are enjoined to preserve the peace towards the United States and to refrain from crime against the public safety, and from violating the laws of the United States and of the States and Territories thereof, and to refrain from actual hostility or giving information, aid or comfort to the enemies of the United States, and to comply strictly with the regulations which are hereby or which may be from time to time promulgated by the President; and so long as they shall conduct themselves in accordance with law, they shall be undisturbed in the peaceful pursuit of their lives and occupations and be accorded the consideration due to all peaceful and law-abiding persons, except so far as restrictions may be necessary for their own protection and for the safety of the United States; and towards such alien enemies, as conduct themselves in accordance with law, all citizens of the United States are enjoined to preserve the peace and to treat them with all such friendliness as may be compatible with loyalty and allegiance to the United States.

And all alien enemies who fail to conduct themselves as so enjoined, in addition to all other penalties prescribed by law, shall be liable to restraint, or to give security, or to remove and depart from the United States in the manner prescribed by Sections four thousand and sixty-nine and four thousand and seventy of the Revised Statutes, and as, prescribed in the regulations duly promulgated by the President;

President Mario Menocal's Statement on Cuba's Decision to Enter the War, 7 April 1917

Cuba cannot remain neutral in this supreme conflict, because the declaration of neutrality would oblige her to treat all belligerents equally, refusing them with equal rigour any access to her ports and imposing on them the same restrictions and prohibitions, which would be in the present case contrary to public sentiment, to the essence of the pacts and moral obligations, moral rather than legal, which bind us to the United States; and would result, lastly, because of our geographical location, in being the cause of innumerable conflicts, the consequences of which it is easy to predict for a friendly and allied nation, and which would prove an inexcusable weakness and condescension for the attitude of implacable aggression unconditionally proclaimed by the Imperial German Government against the rights of all neutral peoples and against the principles of humanity and justice, which constitute the highest note of modern civilisation.
