Abstract
In War & Ethics, Nicholas Fotion undertakes three main tasks. The first is critical: to analyze ‘Just War Theory’ (JWT) in the evolving context of modern warfare between nations and non-nation groups, using various case studies to illustrate the strengths and weaknesses of the theory. The second task is modification: to construct a new Just War Theory to incorporate wars between nations (JWT-Regular) and wars between nations and non-nation groups (JWT-Irregular). The third and final task is defensive: to show that Just War Theory in general, and the twin theory in particular, are useful tools in assessing when a war is just.
