The Socialist Party of the United States in the present grave crisis solemnly reaffirms its allegiance to the principle of internationalism and working-class solidarity the world over, and proclaims its unalterable opposition to the war just declared by the government of the United States.

Modern wars, as a rule, have been caused by the commercial and financial rivalry and intrigues of the capitalist interests in the different countries. Whether they have been frankly waged as wars of aggression or have been hypocritically represented as wars of “defense,” they have always been made by the [ruling] classes and fought by the masses. Wars bring wealth and power to the ruling classes, and suffering, death, and demoralization to the workers.

They breed a sinister spirit of passion, unreason, race hatred, and false patriotism. They obscure the struggles of the workers for life, liberty, and social justice. They tend to sever the vital bonds of solidarity between them and their brothers in other countries, to destroy their organizations, and to curtail their civic and political rights and liberties.
