Query: Lanchester Theory and the Fate of Armed Revolts   Major revolts have recently erupted in parts of the Middle East with
substantial international repercussions. Predicting, coping with and winning
those revolts have become a grave problem for many regimes and for world
powers. We propose a new model of such revolts that describes their evolution
by building on the classic Lanchester theory of combat. The model accounts for
the split in the population between those loyal to the regime and those
favoring the rebels. We show that, contrary to classical Lanchesterian insights
regarding traditional force-on-force engagements, the outcome of a revolt is
independent of the initial force sizes; it only depends on the fraction of the
population supporting each side and their combat effectiveness. We also
consider the effects of foreign intervention and of shifting loyalties of the
two populations during the conflict. The model's predictions are consistent
with the situations currently observed in Afghanistan, Libya and Syria (Spring
2011) and it offers tentative guidance on policy.
