Why would a pacifist oppose the U.S. entry into World War I?
Pacifism is a philosophical and political stance that seeks to reject all forms of violence, including war and militarism, and instead promotes nonviolent methods for resolving conflicts. This can be based on moral, ethical, or religious beliefs, as well as a pragmatic assessment of the effectiveness and consequences of violence.
For pacifists who opposed the U.S. entry into World War I, their opposition likely stemmed from their belief in the futility and destructive nature of war. They may have seen the war as a failure of diplomacy and a failure to find peaceful solutions to international disputes. They may have also been concerned about the loss of life, the physical and psychological harm to soldiers and civilians, and the long-term damage to societies and the global community.
Pacifists also often believe that war only begets more violence, as well as destabilizing political, social and economic systems. Instead, they advocate for non-violent methods such as diplomacy, negotiation, and other forms of peaceful resolution. For these reasons, a pacifist may have opposed the U.S. entry into World War I as a rejection of war and an endorsement of peace.
