In these cases, where there is an unjust aggression, I can only say that it is licit to stop the unjust aggressor. I emphasize the word: "stop". I'm not saying drop bombs, make war, but stop the aggressor. The means used to stop him would have to be evaluated.
Pope FrancisGod never closes off horizons; He is never unconcerned about the lives and sufferings of His children. God never allows Himself to be outdone in generosity.
Pope FrancisLet us ask Mary to help us respond to violence, to conflict and to war, with the power of dialogue, reconciliation and love. She is our mother: may she help us to find peace; all of us are her children!
Pope Francis
