The driving force for conflict is simple proximity—boundaries, once separating people (providing for a measure of isolation) become the issue of a conflict when societies encroach upon one another territorially. If a means to co-exist cannot be immediately found, then conflicts can be hostile, leading to a process by which contact between individuals leads to some resolution. Often, history shows us, the processes of co-existence begins with hostilities, and with the natural passing of polarist individuals, comes the passing of their polarist sentiments, and soon some resolution is achieved.
