For Washington, war usually begins with decisions made behind closed doors and explained through familiar terms such as security, deterrence, and national interest. It is then presented through images of aircraft and missiles moving toward targets thousands of miles away. But for ordinary people, war often arrives more quietly: through the fuel pump, grocery bills, transportation costs, and household budgets that leave less room for basic needs.

The Iran war demonstrated this reality once again. A crisis in the Middle East quickly became connected to one of the world’s most sensitive energy choke points: the Strait of Hormuz. Concerns about disruptions to global energy flows showed how a conflict far from American shores can affect domestic economic conditions. For most Americans, the consequences are not measured through military operations or geopolitical calculations, but through higher energy costs, rising transportation expenses, and pressure on living standards.

Yet the cost of war extends beyond immediate economic effects. Measuring conflict only through oil prices or military spending overlooks a deeper question: what a country cannot invest in because resources are directed toward war.

No national budget is unlimited. Every billion dollars allocated to military operations, weapons purchases, troop deployments, or rebuilding stockpiles cannot be spent simultaneously on infrastructure, education, healthcare, housing, or other public priorities. This is the social opportunity cost of war: the value of needs that receive fewer resources because military commitments take precedence. Defense spending appears clearly in budgets, but the school never built, the infrastructure project delayed, or the public service left underfunded often remain invisible.

A country that spends vast resources on war in the name of security must also ask whether those choices strengthen or weaken the society that security is supposed to protect.

The economic consequences of war also spread through markets, supply chains, and production costs. Conflicts involving major energy-producing regions create uncertainty that eventually reaches households. However, these burdens are not shared equally. A wealthy family may absorb higher fuel or food prices with limited disruption, while a family already struggling with housing, food, and energy costs may be forced to sacrifice another necessity.

The cost of war is therefore not simply national; it is social. Those with the least influence over decisions about war do not necessarily experience the smallest consequences. The civilian impact of conflict extends beyond battlefields. An American worker whose purchasing power declines or a family facing higher living costs also becomes part of the economic burden created by war.

Supporters of military action argue that these costs must be weighed against the dangers of inaction. They maintain that failing to confront threats abroad could create greater instability and eventually produce even higher costs. This argument deserves consideration. Governments have a responsibility to protect citizens and maintain the capabilities needed to respond to serious threats.

However, national security cannot be measured only through military strength. Military power is one element of national power, but it depends on other foundations: a productive economy, reliable infrastructure, an educated workforce, effective institutions, and a society with economic stability. The central question is not whether the United States should maintain defense capabilities, but whether military spending always strengthens security or whether excessive commitments can weaken the foundations that make security possible.

This is where militarism becomes a political issue. Militarism is not simply the use of military force; it emerges when military........
