Taiwan's "porcupine defense" aims to stop a #Chinese invasion. Jay Hsieh & Pete Roongsang say new policies need faster innovation & US aid synchronization in order to succeed.

Taiwan’s defense strategy against a potential cross-strait invasion from China is widely known as the “porcupine defense,” which aims to deny or significantly degrade a rapid ground assault. In a discussion hosted by Tom Galvin, Ying-Chie Hsieh and Pete Roongsang examine Taiwan’s “whole-of-society” resilience program. Their research focuses on three major defense policies enacted since 2022: strengthening the Reserve Component Initiative, reforming the military force structure and people’s defense and establishing the Whole of Society Defense Committee. The conversation stressed the urgent need for greater innovation, synchronization, and speed in preparing Taiwan’s defense. This includes aligning U.S. security assistance with Taiwan’s domestic efforts, specifically by using training alternatives like simulation systems and developing a robust domestic unmanned aerial vehicle industry—to be ready in time.

Since 2022, three major policies have driven the transformation. The first, the strengthening policy on the Reserve Component Initiative. The second one is the strengthening own people’s defense and military force restructure plan. The third, the Whole of a Society Defense Committee.
