After a run of nearly one thousand years, quipped the French philosopher and writer Voltaire, the fading Holy Roman Empire was neither holy nor Roman nor an empire. Today, some two and a half centuries later, the problem, to paraphrase Voltaire, is that the fading liberal world order is neither liberal nor worldwide nor orderly.
The United States, working closely with the United Kingdom and others, established the liberal world order in the wake of World War II. The goal was to ensure that the conditions that had led to two world wars in 30 years would never again arise.
To that end, the democratic countries set out to create an international system that was liberal in the sense that it was to be based on the rule of law and respect for countries' sovereignty and territorial integrity. Human rights were to be protected. All this was to be applied to the entire planet; at the same time, participation was open to all and voluntary.
