Stephen Spiro (1939–2007) was a political activist known for his opposition against the Vietnam War and his advocacy of an ideology that opposes abortion, capital punishment, assisted suicide, and euthanasia. Opposing the Vietnam war based on the theory of Just War, he objected to being conscripted, but as the law only allowed for conscientious objection to all wars, he was convicted of avoiding conscription and given a suspended sentence of five years. He was later pardoned by President Gerald Ford.
