III. Safeguarding Peace

From The Catechism of the Catholic Church

2309
The strict conditions for legitimate defense by military force require rigorous
consideration. the gravity of such a decision makes it subject to rigorous
conditions of moral legitimacy. At one and the same time:
– the damage inflicted by the aggressor on the nation or community of nations
must be lasting, grave, and certain;
– all other means of putting an end to it must have been shown to be
impractical or ineffective;
– there must be serious prospects of success;
– the use of arms must not produce evils and disorders graver than the evil to
be eliminated. the power of modem means of destruction weighs very heavily in
evaluating this condition.
