Just war
the rules of war which permit a religious person to fight, found in Christian and Sikh teachings.
The ‘Just War’ theory
Jus ad bellum
a set of criteria that are to be consulted before engaging in war in order to determine whether entering into war is permissible
Jus in bello
the law that governs the way in which warfare is conducted
Jus ad bellum: Just Cause
There must be a Just Cause, the target country must deserve it. These include defending a nation under attack or stopping a dictator
Jus ad bellum: Legitimate authority
The war must be started and controlled by a legitimate authority i.e. by the political system, not the military.
Jus ad bellum: Right intention
There must be a just intention / motive for going to war e.g. to restore peace or right a wrong
Jus ad bellum: Probability of success
There must be a reasonable chance of winning, the good gained must outweigh the suffering.
Jus ad bellum: Last resort
The war must be a last resort – all other options must have been attempted.
Jus ad bellum: Proportionality
There must be “proportionality”: waging a war must be proportionate to the evil or harm that is being threatened.
Jus in bello: Principle of Discrimination
Principle of Discrimination means that non-combatants should not be targeted in a war. It is also not acceptable to target civilian areas for bombing.
Jus in bello: Proportionality of Means to ends
Proportionality of the means to ends clause means that when actually fighting the war, the amount of force used must always be proportionate to the threat.
application to weapons of mass destruction: Nuclear Weapons
The fall out from a nuclear bomb is unknowable. The heat from an exploded bomb reaches several million degrees.
application to weapons of mass destruction: Chemical Weapons
When used as far back as The First World War, mustard gas and phosgene gas caused blindness, lung damage and death.
application to weapons of mass destruction: Biological Weapons
These include bacteria and viruses, and in some ways biological weapons are the most feared form of warfare.
