Words that build bridges

For decades, American national security was defined by relatively narrow terms: defending physical borders from military threats and terrorism. Today, that definition has expanded to include domains that would have once been considered purely economic. From artificial intelligence to pharmaceutical supply chains and even the price of consumer goods, the boundary between military defense and domestic economic policy has increasingly faded. Driven by shifting strategic doctrine and reinforced by recent legal developments, the executive branch now routinely uses “national security” to justify intervention in trade, energy, and technology. This expansion of what can be understood as “security inflation” is a transformation in how the U.S. government defines risk, power, and its own role in the economy.

Origins of Expansion

The expansion of national security is the result of a series of overlapping shocks that exposed the fragility of the global economic system. Rising geopolitical competition between the United States and China has reframed economic interdependence as a strategic risk. Technologies such as artificial intelligence became a place of competition. At the same time, the COVID-19 pandemic revealed the extent to which critical supply chains were reduced abroad. Shortages of medical equipment, pharmaceuticals, and basic goods demonstrated that efficiency-driven globalization had created hidden issues. More recently, geopolitical instability has reinforced this perspective. Disruptions to global energy markets and trade routes, including tensions surrounding the Strait of Hormuz, have shown how quickly distant conflicts can turn into domestic economic consequences. Together, these developments have encouraged policymakers to treat economic systems as strategic infrastructures requiring protection and control.

Redefining “National Security”

At the core of this shift is a fundamental redefinition of what counts as a threat. The United States Trade Representative’s (USTR) 2026 Trade Policy Agenda explicitly states that “economic security is national security,” signaling that economic systems are now viewed as integral to the defense strategy. Federal agencies have begun to operationalize this broader definition in concrete ways. The Environmental Protection Agency (EPA) now identifies cyber-attacks on critical infrastructure, artificial intelligence misuse, intellectual property theft, climate disruptions, and pandemics as active national security threats. What links these diverse risks is their potential to disrupt the functioning of the state. In this sense, vulnerability is no longer defined by physical exposure, but by systemic dependence.

This shift is reinforced by broader changes in U.S. strategic thinking. Analyses of recent National Security Strategy (NSS) frameworks by the Center for Strategic and International Studies (CSIS) show a move away from prioritizing global democratic expansion toward a more pragmatic focus on economic and technological dominance. Maintaining leadership in industries such as artificial intelligence, quantum computing, and energy is now treated as a strategic defense asset requiring government oversight.

This represents a historic departure from the late-20th-century consensus of free-market globalization. Rather than assuming that open markets produce stability, policymakers now view reliance on foreign supply chains as a structural vulnerability. The role of the state is shifting accordingly, from facilitating markets to actively shaping them. The question is no longer whether the government should intervene, but where and how.

The Healthcare Paradox

The consequences of this shift become most visible when applied to specific industries. The pharmaceutical supply chain offers a particularly revealing case. Currently, the United States relies heavily on geopolitical rivals, such as China and India for Active Pharmaceutical Ingredients (APIs), the essential components required for most medications. From a traditional economic perspective, this arrangement reflects efficiency: production occurs where it is cheapest. From a security perspective, however, it represents a dangerous dependency. In response, policymakers have proposed tariffs and domestic production mandates to reduce reliance on foreign suppliers. Yet these measures expose a central tension within security-driven policy. While intended to strengthen resilience, they can generate immediate and tangible costs. Tariffs designed to incentivize domestic production increase manufacturing expenses, raising the risk of drug shortages in the short term.

This condition becomes even more noticeable in the application of Section 232 tariffs, which allows the executive branch to restrict imports on national security grounds. When applied to raw materials such as steel, aluminum, and specialized plastics, these tariffs raise the manufacturing cost of producing essential medical equipment, such as hospital beds and syringes. In this way, a policy justified in the name of security can undermine another part of it. If public health is itself a national security concern, then increasing the cost of healthcare infrastructure complicates the very logic used to justify intervention.

Executive Power and Economic Consequences

This expansion of national security into economic policy has also altered the balance of power within the federal government. A recent 2026 Supreme Court decision has granted the executive branch broad discretion in defining what constitutes a national security threat in the context of trade. By limiting judicial oversight, the ruling effectively allows the president to impose tariffs and reshape industrial policy with minimal constraint, so long as these actions are framed in terms of security.

This legal shift amplifies the effects of security inflation. As the definition of security expands, so too does the scope of executive authority. Policies that would traditionally require legislative debate can now be implemented unilaterally, justified by the urgency of national defense.

At the same time, these policies carry broader economic consequences. Efforts to reorganize supply chains around resilience rather than efficiency reflect a global transformation. The Observer Research Foundation describes the transition from “just-in-time” to “just-in-case” production models. While this shift may reduce exposure to external shocks, it also introduces higher costs into the system, contributing to long-term inflationary pressures. In prioritizing security, policymakers are effectively accepting economic trade-offs as a permanent feature of the system rather than a temporary response to the crisis.

Conclusion

The merging of economic policy and national security marks a fundamental transformation in American governance. As the definition of security continues to expand, it becomes an increasingly powerful justification for state intervention across nearly every sector of the economy. However, while the expansion of national security reflects real issues, it also risks normalizing a permanent place of economic intervention justified by crisis. If nearly any policy can be framed as a matter of security, the distinction between necessity and political choice begins to go away. Ultimately, security inflation redefines the boundaries of political authority. In expanding what counts as security, the United States is constructing a new model of governance in which the logic of defense increasingly structures everyday economic life. ■
