War, however, does seem to incorporate system-level factors, such as the regional balance among great powers. The example suggests that elements of realism may continue to be useful in the explanation of behaviour in the aggregate, such as the relative propensity of regions or time periods to experience interstate war. The authors' "broadest significant conclusion" is that the domestic variant of the international interaction game receives support from the historical record, while realism does not (266-67). Furthermore, war does seem to occur with reason, but not necessarily to the benefit of the general public. To conclude, this book is essential reading; it provides a superb example of how deductive logic, statistical evidence and in-depth knowledge from cases can be combined to achieve scientific progress.
