             Following the principle of a just cause is the necessity of war to be waged by a lawful authority. This means that a governing body of authority only has the power to call a just war, as it must be a collective sovereign plan to wage war against an enemy nation (Spaeth, 99). When Canada brought itself into World War II, they had complete control over their own foreign affairs due to the 1932 Statute of Westminster, thus the government was a lawful authority, and was justified in bringing the nation into the war.

This principle resembles the principle of double effect, as both hold that evil intentions cannot bring about a greater good, as the ends do not justify the means.
             Along with just cause, lawful authority, and right intention, just means is the fourth principle necessary for a just war. The primary aim of a defensive war is "to immobilize or destroy the armed might of the enemy" (Spaeth, 99).

In spite of this, there are some restrictions to the means, which a nation can pursue with justice. Firstly, the
             immunity of the noncombatants is of the greatest importance. Many citizens in any given enemy country are not responsible for the evil committed through the country's aggression and therefore cannot be p...
