War, from the Western perspective, is not a solitary endeavor. Partnerships of all types serve as a foundation for the projection of power and the employment of force. Waging War argues that these institutions of interstate violencenot just the technology, capability, and level of professionalism and training of armed forcesserve as ready mechanisms to employ force. However, these institutions are not always well designed, and do not always augment fighting effectiveness as they could, sometimes serving as drags on state capacity. At the same time, the net benefit of having this web of partnerships, agreements, and alliances is remarkable. It makes rapid response to crisis possible, and facilitates countering threats wherever they emerge.

Utilizing what the author calls a realist institutionalist agendaone that understands institutions as conduits of capabilitythis book lays out which institutional arrangements lubricate states' abilities to advance their agendas and prevail in wartime, and which components of institutional arrangements undermine effectiveness and cohesion, and increase costs to states. It demonstrates and tests the argument in five empirical chapters, examining the cases of the first Gulf War, Kosovo, Afghanistan, Iraq, and Libya. Each case has distinct lessons as well as important generalizations for contemporary multilateral warfighting.
