Answer:
War is generally considered justified when it is used as a last resort to defend against aggression or to protect the fundamental rights of individuals. It is not justified when it is used as a means of furthering political, economic, or personal interests, or when it is used to perpetrate acts of aggression or injustice. The criteria for determining whether a war is just can include the cause for which it is being fought, the means by which it is being conducted, and the probable consequences of the conflict. In general, it is important to consider the principles of just cause, right intention, and proportionality when evaluating the justice of a war. However, it is important to note that the concept of justice in war is a highly contested and complex issue, and different individuals and groups may have different perspectives on what constitutes a just war.
