👉 The "just weapon" refers to a concept in just war theory that posits a weapon is permissible only if it is used as a last resort and with the intention of restoring peace or defending against aggression, rather than for personal gain or excessive force. It emphasizes that the use of lethal force must be proportionate to the threat and aimed at minimizing harm to non-combatants. This principle underscores the moral responsibility of those who decide to use force, insisting that such actions must be justified by a just cause and conducted with the utmost restraint to prevent unnecessary suffering.
