The South China Sea, more than any other part of the world, best illustrates, once again, what would be the cost of a U.S. decline, or even of a partial U.S. withdrawal from its forward military bases.
As such, the South China Sea shows what exactly the United States provides the world that is now at risk, and concomitantly, what the bad things are that could happen were the world, in an air and naval sense, to become truly multipolar.

Because the United States dominates the Western Hemisphere, and has power to spare to affect the balance of power in the Eastern Hemisphere, the U.S. not only keeps the peace (aside from small wars that erupt here and there), it guards the global commons, that is, the sea lines of communication that allow for
The fact that Russia is still constrained in its attempts to seriously undermine the sovereignty of states in Eastern and Central Europe; the fact that the Middle East has so far at least avoided an interstate Holocaust of sorts; the fact that India and Pakistan have not engaged in a full-scale war in decades, and have never used their nuclear weapons; the fact that North Korea merely threatens South Korea and Japan with large-scale military aggression rather than actually carrying it out, is all in large measure because of a U.S. global security umbrella.

The fact that small and embattled nations, be it Israel or Georgia, can even exist is because of what ultimately the U.S. military provides. Indeed, it is the deployment of American air and naval platforms worldwide that gives American diplomacy much of its signal heft, which it then uses to support democracy and freer societies everywhere.
Substantially reduce that American military presence, and the world-and the South China Sea, in particular- looks like a very different place.
The United States keeps China honest: limiting China's aggression mainly to its maps, so that China's diplomats and navy act within reason. That is not to say that the United States is pure in its actions and China automatically the villain. For example, the United States conducts classified reconnaissance activities on a regular basis against China in the Western Pacific that it would have difficulty tolerating were they directed at its own nearby waters by a rival great power.
What the United States provides to the nations of the South China Sea region is less the fact of its democratic virtue than the fact of its raw power, which counters that of China. It is the balance of power between the United States and China that ultimately keeps Taiwan, Vietnam, Malaysia, the Philippines, Indonesia, and Singapore free, able to play one great power off against the other. And within that space of freedom, regionalism, in the form of ASEAN, can emerge as a power in its own right. Yet such freedom cannot be taken for granted.
