Conflict within and among nations is a constant feature throughout the world, with prevailing levels of conflict being concentrated in the poor countries. The authors present an integrated model connecting the theory of internal conflict and the theory of lateral pressure by making simulations of two cases, one, a small, weak country with high population density and low technology level, and the second, a large, strong country with a high level of technology. They conclude that such a model relates only to parts of the puzzle that makes up conflict dynamics.
