Balance of Power

Twenty years ago, Robert Cooper explained the relationship between nations states and the balance of power.

To understand the present, we must first understand the past, for the past is still with us. International order used to be based either on hegemony or on balance. Hegemony came first. In the ancient world, order meant empire. Those within the empire had order, culture and civilisation. Outside it lay barbarians, chaos and disorder. The image of peace and order through a single hegemonic power centre has remained strong ever since. Empires, however, are ill-designed for promoting change. Holding the empire together – and it is the essence of empires that they are diverse – usually requires an authoritarian political style; innovation, especially in society and politics, would lead to instability. Historically, empires have generally been static.

In Europe, a middle way was found between the stasis of chaos and the stasis of empire, namely the small state. The small state succeeded in establishing sovereignty, but only within a geographically limited jurisdiction. Thus domestic order was purchased at the price of international anarchy. The competition between the small states of Europe was a source of progress, but the system was also constantly threatened by a relapse into chaos on one side and by the hegemony of a single power on the other. The solution to this was the balance-of-power, a system of counter-balancing alliances which became seen as the condition of liberty in Europe. Coalitions were successfully put together to thwart the hegemonic ambitions firstly of Spain, then of France, and finally of Germany.

But the balance-of-power system too had an inherent instability, the ever-present risk of war, and it was this that eventually caused it to collapse. German unification in 1871 created a state too powerful to be balanced by any European alliance; technological changes raised the costs of war to an unbearable level; and the development of mass society and democratic politics, rendered impossible the amoral calculating mindset necessary to make the balance of power system function. Nevertheless, in the absence of any obvious alternative it persisted, and what emerged in 1945 was not so much a new system as the culmination of the old one. The old multi-lateral balance-of-power in Europe became a bilateral balance of terror worldwide, a final simplification of the balance of power. But it was not built to last. The balance of power never suited the more universalistic, moralist spirit of the late twentieth century.
