What is the Utilitarian response to war?
In Utilitarianism, the end justifies the means. Strictly speaking, a country wouldn't need a just cause to go to war as long as they had the right intention
- The greatest happiness for the greatest number of people.
A utilitarian would not support selfish motives.
However, utilitarians would be happy for the military or the President to make up a threat so long as the ensuing war made the world a better place.
Rule Utilitarians may have a different approach, arguing that a world where people go to war without a just cause would be an unstable world.
Therefore the Just War Criteria, although in many cases not utilitarian, may be necessary to make the world a better place.
