Abstract

In this contribution, I defend the standard list of jus ad bellum principles. In The Ethics of War and the Force of Law: A Modern Just War Theory, Uwe Steinhoff endorses only three principles of jus ad bellum (right intention, just cause, and proportionality) and claims that the others are redundant. I argue that, although fundamentally all jus ad bellum principles can be reduced to proportionality, in practice it is vital to retain the main jus ad bellum criteria as separate principles.
