|First Afghan War, 1842|
- Legitimate Authority: Requiring that only legitimate officials may decide to resort to force is one way to protect against arbitrariness.
- Just Cause: The three standard acceptable causes are self-defense, recovery of stolen assets and punishment for wrong-doing.
- Peaceful Intention: The intention is to use force to achieve peace, using force to restrain and minimize force.
- Last Resort: Before turning to war, all reasonable approaches to a peaceful resolution need to be employed.
- Reasonable Hope of Success: In going to war, there must exist the reasonable expectation of successfully obtaining peace and reconciliation between the warring parties.
- Proportionality: The suffering and devastation of war must not outweigh whatever benefits may result from war.
- Discrimination or Noncombatant Immunity: The means of warfare must discriminate between combatants and noncombatants.
