- CSIS wargaming projects a Chinese invasion would cause the loss of two U.S. carrier strike groups and over 900 aircraft.
- Taiwan produces over 90% of the world’s most advanced semiconductors, making the island a single point of failure for global tech.
- Current military models often fail to account for the simultaneous impact of a Middle East conflict and a Taiwan contingency.
The Wargame Baseline
A potential Taiwan invasion acts as a primary trigger for global instability. Military planners increasingly view a cross-strait conflict through the lens of attrition. Recent CSIS wargaming tracks a sequence beginning with massive missile barrages against airbases and ports. The goal for the People’s Liberation Army is to achieve rapid air superiority over the Taiwan Strait.
Historical precedents like Operation Desert Storm suggest that achieving total air dominance takes weeks of systematic strikes. Modern wargaming projections for a Taiwan scenario suggest a faster, more violent opening phase. U.S. intervention, while not strictly mandated by a formal defense treaty, remains the core assumption of these simulations. The Taiwan Relations Act provides the legal framework for diplomatic and military support, but current projections indicate the cost of that support would be catastrophic. Analysts estimate the loss of at least two U.S. carrier strike groups and hundreds of aircraft in the initial weeks of a conflict, according to the full CSIS report.
Chinese officials maintain that these military preparations are purely defensive measures intended to deter independence movements. Beijing argues that the presence of U.S. naval assets in the region constitutes an illegal provocation and an infringement on national sovereignty. They contend that any conflict would be a domestic matter rather than an international crisis.
The Semiconductor Blind Spot
The strategic calculus changes when you factor in the global semiconductor industry. Taiwan hosts the world’s most advanced chip fabrication facilities, producing over 90% of the most sophisticated semiconductors. Most military wargames, including those from RAND, focus on the kinetic outcome of an invasion. These models often assume the destruction of these fabs, yet they struggle to account for China’s potential strategic incentive to capture the facilities intact.
The discrepancy creates a major blind spot. If the PLA manages a successful amphibious assault, they inherit a neutralized or destroyed tech hub. If they fail, the global economy suffers an immediate, irreversible supply shock. The 2025 DOD report highlights the ongoing expansion of Chinese military power, but the economic fragility of the tech sector acts as a multiplier. A single advanced fab costs roughly $20 billion to build and requires years of specialized talent to operate. Replacing that capacity in an active war zone is impossible.
The Two-Front Risk
The most significant variable currently missing from most models is the “simultaneous crisis” scenario. Intelligence assessments, including the 2025 DNI Threat Assessment, warn that U.S. resources are already stretched. A conflict in the Middle East, such as the one described in recent Defense Priorities analysis, would force the Pentagon to choose between two major theaters.
When you combine a 50% reduction in available naval assets due to a Middle East deployment with the projected 900-aircraft loss rate from the CSIS Taiwan simulation, the math for a successful intervention breaks down. The risk is not just the loss of the island. It is the collapse of the global economic order that depends on the flow of goods through those specific maritime lanes. None of those outcomes are popular. All of them are on the table.
