jus ad bellum): aside from the rhetorical use of such an expression to characterize any war for the side offering a justification, there is a technical use applicable in addition to war justified on the basis of self-defense (just cause). Just war offers a doctrine in which the use of force is justified to punish wrongs and protect the innocent in order to uphold standards of civilized conduct.
Just war is a specific concept of how warfare might be justified, typically in accordance with a particular situation, or scenario, and expanded or supported by reference to doctrine, tradition, or historical commentary. The tradition began in the ancient Greek society, and was later developed by a number of Christian theologians. The just war tradition includes a great variety of thinkers who advocate different ways of employing shared concepts (just cause, good intentions, proportionality, discrimination, etc.) for purposes of ethical reflection and judgment about the use of force and the tradition has been expanded to include non-traditional forms of warfare, such as guerrilla war and humanitarian interventions.
Just War is a novel by Lance Parkin from the Virgin New Adventures. The New Adventures were based on the long-running British science fiction television series Doctor Who. The novel featured the characters of the Seventh Doctor, Bernice Summerfield (known as Benny), Chris Cwej and Roz Forrester.
