Why Wars Widen A Theory of Predation and Balancing
This work explains how wars are most likely to escalate when the effects of warfare are limited. The author demonstrates that total wars during the modern era were very violent and were far less likely to spread, yet the cost of warfare is falling making future conflicts more likely to spread.
'Haldi's model serves as a pertinent explanation of why some of the wars of the past three centuries have spread whilst others have remained isolated, as well as a useful tool for predicting the likelihood of war-widening in the twenty-first century.'
