It is not true that were the Soviet Union to disappear the remaining states could easily live in peace. - Kenneth Waltz

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.

The transitory interests of royal houses may be advanced in war; the real interests of all people are furthered by the peace.

If we are to have peace, we must learn loyalty to a larger group. And before we can learn loyalty, the thing to which we are to be loyal must be created.
