BILL GERTZ: China’s Secret Military Plan: Invade Taiwan by 2020.

China has drawn up secret military plans to take over the island of Taiwan by 2020, an action that would likely lead to a larger U.S.-China conventional or nuclear war, according to newly-disclosed internal Chinese military documents.

The secret war plan drawn up by the People’s Liberation Army (PLA), the Chinese Communist Party’s armed forces, calls for massive missile attacks on the island, along with a naval and air blockade that is followed by amphibious beach landing assaults using up to 400,000 troops.

The plans and operations are outlined in a new book published this week, The Chinese Invasion Threat by Ian Easton, a China affairs analyst with the Project 2049 Institute, a think tank.

The danger of a Taiwan conflict has grown in recent years even as current tensions between Washington and Beijing are mainly the result of U.S. opposition to Chinese militarization in the South China Sea and China’s covert support of North Korea’s nuclear and missile programs.

“Of all the powder kegs out there, the potential for a war over Taiwan is by far the largest and most explosive,” the 290-page book states, adding that the growing likelihood of a war over Taiwan will dominate worries within the Pentagon for years to come.

It’s difficult to imagine how China would get more out of forcibly annexing Taiwan than they’d lose in a major shooting war — but then the decision to go to war is rarely made so rationally.
