  We propose a "social physics" model for two-group conflict. We consider two
disputing groups. Each individual i in each of the two groups has a preference
si regarding the way in which the conflict should be resolved. The individual
preferences span a range between +M (prone to protracted conflict) and --M
(prone to settle the conflict). The noise in this system is quantified by a
"social temperature." Individuals interact within their group and with
individuals of the other group. A pair of individuals (i, j) within a group
contributes-si * sj to the energy. The inter-group energy of individual i is
taken to be proportional to the product between si and the mean value of the
preferences from the other group's members. We consider an equivalent-neighbor
Renyi-Erdos network where everyone interacts with everyone. We present some
examples of conflicts that may be described with this model.
