The "Criteria for War" refers to the conditions that justify the initiation of armed conflict. These criteria often include just cause, legitimate authority, right intention, probability of success, proportionality, and last resort. These principles help determine whether a war is morally and legally justified, guiding nations in their decision-making processes. In international relations, the criteria are often discussed in the context of Just War Theory, which has roots in philosophical and religious traditions. Adhering to these criteria aims to minimize unnecessary suffering and ensure that military actions are taken for the right reasons, promoting peace and stability in the long term.
