The Just War Doctrine

Discuss the relevancy of the just war doctrine. Is the language of the doctrine still relevant in today's world? Can war ever be justified? If so under what circumstances? Is our current perspective on the "justness" of war gendered, and if so in what ways? How might this be addressed moving forward? Finally, rather than a "Just War" doctrine, what might a doctrine look like that emphasizes peacemaking and peacebuilding?
