Another factor is the unusual speed with which the Chinese economy has expanded to its true potential, thanks to the focused investment made possible by an authoritarian government … and also thanks to that government’s utter disregard for the natural environment and for the rights of everyday Chinese people.

“The economic model that propelled China through three decades of meteoric growth appears unsustainable,” Andrew Erickson, a Naval War College analyst, told the U.S.-China Economic and Security Review Commission.

What Erickson described as China’s “pent-up national potential” could begin expiring as early as 2030, by which point “China will have world’s highest proportion of people over 65,” he predicted. “An aging society with rising expectations, burdened with rates of chronic diseases exacerbated by sedentary lifestyles, will probably divert spending from both military development and the economic growth that sustains it.”

Wisely, American political and military leaders have made the investments necessary to sustain U.S. undersea power for at least that long. After a worrying dip in submarine production, starting in 2012 the Pentagon asked for—and Congress funded—the acquisition of two Virginia-class submarines per year for around $2.5 billion apiece, a purchase rate adequate to maintain the world’s biggest nuclear submarine fleet indefinitely.

The Pentagon is also improving the Virginia design, adding undersea-launched drones, extra missile capacity and potentially a new anti-ship missile.

Given China’s place in the world, its underlying national trends and America’s pointed advantage in just that aspect of military power that’s especially damaging to Chinese plans, it seems optimistic for PLA officers to assume they can launch an attack on China’s neighbors without first knocking out U.S. forces.

Not that a preemptive strike would make any difference, as the only American forces that truly matter for containing China are the very ones that China cannot reach.

For they are deep underwater.
