Semiconductors are the backbone of the modern world. They power everything from smartphones to fighter jets, yet most people don’t give them a second thought—until their new PlayStation is out of stock for a year. But beyond frustrating gamers, semiconductor supply chains are one of the most critical national security vulnerabilities today. Governments and corporations alike depend on a stable, secure supply of chips, and any disruption could have consequences far beyond tech shortages.
This isn’t the first time semiconductors have taken center stage in the national security conversation. As I wrote in my previous article about Taiwan Semiconductor Manufacturing Company (TSMC), corporate security has evolved from simple office protocols to a battleground of state-backed espionage, cyber warfare, and intellectual property theft. TSMC, as the world’s most important chipmaker, has been a prime target for China’s aggressive push toward technological self-sufficiency. Entire teams of engineers have been poached, cyberattacks have tested the company’s defenses, and the geopolitical stakes surrounding Taiwan have only escalated.
The global semiconductor supply chain is a logistical masterpiece that, unfortunately, also happens to be a geopolitical nightmare. The majority of the world’s most advanced chips come from Taiwan, with a handful of companies, most notably TSMC, dominating production. The issue? Taiwan sits right in China’s crosshairs, and any escalation in the Taiwan Strait would send shockwaves through the global economy. The United States, realizing that the lifeblood of its defense and tech industries is concentrated on an island that China wants, has been scrambling to onshore production. The CHIPS Act, a $52 billion initiative, aims to bring semiconductor manufacturing back to the U.S., but there’s no overnight fix for decades of offshoring.
Corporations are also feeling the heat. Tech giants, defense contractors, and even automakers are caught in a balancing act between securing stable chip supplies and not angering China, which remains a key market and manufacturing hub. Intel, NVIDIA, and Qualcomm, for example, rely on Taiwan and South Korea for chip fabrication but still need China for assembly and packaging. The problem is that China is no stranger to using economic leverage as a weapon, and its “dual circulation” policy aims to reduce reliance on foreign tech while making the world more dependent on Chinese supply chains. The message is clear: anyone who gets in the way of Beijing’s goals could find themselves locked out of the world’s second-largest economy.
Meanwhile, corporate espionage in the semiconductor industry is an arms race in itself. China has been accused of aggressive intellectual property theft, with former engineers from TSMC and other firms mysteriously reappearing in Chinese chip startups. The U.S. has responded by imposing export controls, restricting China’s access to advanced chips used in AI and military applications. Washington even pressured the Dutch government to block ASML, the only company capable of producing extreme ultraviolet lithography machines, from selling to China. In response, China is doubling down on domestic production, but catching up in semiconductor manufacturing is a bit like trying to learn brain surgery from a YouTube tutorial—technically possible, but the results are probably going to be messy.
If semiconductor security collapses, the effects won’t just be limited to tech companies. The defense sector, financial systems, infrastructure, and even basic consumer goods would be thrown into disarray. The F-35 fighter jet alone relies on over 300 semiconductor suppliers, and any disruption could ground fleets worldwide. Banks that rely on high-speed transactions powered by advanced chips would be vulnerable. Even household appliances could be affected—imagine a world where your smart fridge stops working, and you actually have to check if you’re out of milk. Chaos.
The future of national security depends on stable and secure semiconductor supply chains. Governments are working to mitigate risks by diversifying production and funding domestic chip manufacturing, but the reality is that semiconductors will remain a key geopolitical flashpoint for years to come. Whether it’s through diplomatic maneuvers, strategic alliances, or cutting-edge R&D, the race for semiconductor dominance isn’t just about technology—it’s about who controls the future.
