- Anti-imperialism: Socialists believed that the war was a capitalist conflict fought over control of colonies and resources, rather than a struggle for democracy or justice. They argued that the working class had no interest in fighting for the interests of the ruling class.
- Pacifism: Many socialists were pacifists who believed that war was always wrong and should be avoided at all costs. They argued that the war would only lead to more violence and destruction, and that it would not solve the underlying problems that caused it.
- Class Struggle: Socialists believed that the war would intensify class conflict and lead to a revolution of the working class. They argued that the war was a distraction from the real struggle between the working class and the capitalist class.
- Anti-militarism: Socialists were opposed to the militarization of society and the idea of conscription. They argued that the war would lead to a permanent military state and that it would erode civil liberties.
- Opposition to the Wilson administration: Socialists were critical of President Woodrow Wilson's policies, which they saw as pro-business and anti-labor. They argued that Wilson was not committed to the interests of the working class and that his policies would only worsen the conditions of the poor.
In conclusion, socialists opposed US participation in World War I for a variety of reasons, including anti-imperialism, pacifism, class struggle, anti-militarism, and opposition to the Wilson administration.
