External pressure seems to produce internal unity.

Each state pursues its own interest's, however defined, in ways it judges best. Force is a means of achieving the external ends of states because there exists no consistent, reliable process of reconciling the conflicts of interest that inevitably arise among similar units in a condition of anarchy.

Is it capitalism or states that must be destroyed in order to get peace, or must both be abolished?

In anarchy there is no automatic harmony .

The most important causes of political arrangements and acts are found in the nature and behavior of man.

With many sovereign states, with no system of law enforceable among them, with each state judging its grievances and ambitions according to the dictates of its own reason or desire - conflict, sometimes leading to war, is bound to occur.

War may achieve a redistribution of resources, but labor, not war, creates wealth.
