Militaries function in a professional manner; they develop and respect their doctrine, operational principles, fighting techniques and values. Their performances are not random or incidental. The suggested paradigm calls for leveraging the constraining elements that are latent in military professionalism. Talking professional language and adopting the professional way of thinking that underlies militaries' conduct makes it possible to identify and focus upon the core interests of a military in any given lawful war - those that ought to be taken into consideration - alongside those that can be sacrificed for the sake of the humanitarian concerns, while still allowing the military mission to be achieved. Indeed, leveraging professional standards and norms would establish a reasonable modus vivendi for a military, while allowing substantial new space for the humanitarian mission of the law.
