Pacifism is a theory on warfare that advocates for the rejection of violence and war as a means to resolve conflicts. It promotes peaceful solutions, non-violent resistance, and the belief in the inherent value of all human life. Pacifists argue that war only perpetuates more violence and suffering, and that conflicts should be resolved through dialogue, diplomacy, and non-violent means. This theory opposes any form of aggression or military intervention and emphasizes the importance of promoting peace, justice, and equality.
