Palantir’s Defense Chief Sees China Threat to Taiwan Over AI

Bloomberg | Maggie Eastland

Taiwan's critical position in global artificial intelligence hardware manufacturing has heightened incentives for Chinese President Xi Jinping to forcibly control the island, according to Mike Gallagher, head of defense at Palantir Technologies Inc. Speaking on 28 October 2026, the former US Congressman warned that accelerating artificial intelligence capabilities have intensified strategic competition between Washington and Beijing over key technologies.

Taiwan produces the vast majority of advanced semiconductors required to train and deploy complex machine-learning models worldwide. Hardware bottlenecks now dictate geopolitical stakes. Beijing's military calculus increasingly merges long-standing territorial unification objectives with an imperative to dominate critical semiconductor infrastructure. A military crisis across the Taiwan Strait would immediately sever global microchip flows, triggering severe economic downturns and stalling global software innovation. Consequently, Western defence planners and technology firms are accelerating supply chain diversification to mitigate potential blockades, while preparing for prolonged technological decoupling in East Asia.

Comment

The concentration of extreme ultraviolet lithography processing within TSMC's Fab 18 in Tainan creates a single point of failure that cannot be offset by distributed manufacturing. While Western nations invest in domestic semiconductor foundries, building leading-edge nodes below three nanometres requires highly specialized chemical supply chains and optics from ASML that take years to establish. Any operational interruption to Taiwanese cleanrooms creates an immediate physical ceiling on global hardware output for defence and commercial software development. The physical realities of semiconductor fabrication limit rapid industrial surging.

This industrial bottleneck fundamentally alters military procurement cycles for autonomous systems relying on high-density processing units. If cross-strait supply chains break, Western defence primes face multi-year delays in producing guided munitions and automated command platforms that depend on custom silicon. Consequently, stockpiles of precision-guided weapons like the AGM-158C LRASM will hit hard manufacturing ceilings long before alternative foundries achieve operational yield rates.

Strategic Question for Discussion

If a cross-strait emergency disables TSMC's Fab 18, which factor will exert a greater constraint on Western defence industrial replenishment — the multi-year lead time for ASML lithography equipment or the lack of domestic advanced packaging facilities?

The available evidence points toward advanced packaging and cleanroom tooling as the primary bottleneck, rather than raw wafer fabrication capacity alone. While greenfield foundries in North America and Europe can construct physical facilities, replicating the specialized ecosystem surrounding ASML lithography and backend assembly takes significantly longer. Consequently, defence industrial bases would likely face a prolonged structural deficit in sub-seven-nanometre silicon regardless of fast-tracked capital expenditure.
