For the last thirty years, the United States has mostly treated homeland security as a series of separate events: a hurricane, a bombing, a pandemic, or a cyber outage. Each has a beginning and an end, and each brings in the familiar federal, state, and local agencies. This system has saved lives. However, it is not designed for situations in which an adversary tries to disrupt electric power, water systems, ports, and communications simultaneously while also slowing public decision-making.

This is not a call to bring back air-raid wardens, warning sirens, or fallout-shelter signs. Cold War civil defense was uneven, underfunded, and often easy to make fun of. Still, its basic premise was sound. A country is harder to coerce when its people, local governments, and essential services can continue to function after someone has tried to knock them down.

Early Roots in Total War

Civil defense in the United States did not begin with the atomic bomb. German air raids on British cities during the First World War showed that modern war could reach civilians far behind the front lines. In 1916, Congress created the Council of National Defense to deal with the broader problem of mobilization. The Council linked industrial production, transportation, public welfare, and civilian morale to the war effort, and encouraged states to establish their own defense organizations. After 1918, most of that activity was dismantled. Distance and two oceans again seemed like enough.²

World War II closed that gap. On May 20, 1941, well before Pearl Harbor, President Franklin D. Roosevelt established the Office of Civilian Defense within the Office for Emergency Management. The records of the office, preserved in Record Group 171 at the National Archives, show that its duties were much broader than public relations. They included fire defense, rescue, emergency medical services, communications, camouflage, warning, evacuation, and the recruitment and training of volunteers. Washington was trying to organize the home front before an attack, not after one.³

Executive Order 9562 ended the Office on June 30, 1945. The wartime emergency had passed, but the underlying question had not: how much peacetime preparation was the country willing to support?

Why Civil Defense Was Built for the Nuclear Age

That question returned in August 1949, when the Soviet Union tested an atomic bomb. The communist victory in China and the outbreak of war in Korea followed shortly afterward. American planners now had to assume that their cities could be targets. The issue was no longer whether civilians might be affected by war, but whether the United States could still govern, produce, communicate, and fight after an attack on its population centers.

Congress passed the Federal Civil Defense Act of 1950, and President Truman signed it into law on January 12, 1951.⁴ The statute created the Federal Civil Defense Administration, but left most of the actual work to states and cities. Washington would provide guidance, training, grants, and technical assistance. Governors, mayors, police and fire chiefs, hospitals, schools, utilities, employers, and volunteers would have to carry out the work. That division of responsibility was intentional. The federal government had concluded that civil defense could not be run from an office in Washington.

The program’s public face was easier to remember than the statute. In 1952, the government introduced “Duck and Cover,” with Bert the Turtle telling schoolchildren to get under their desks after seeing the flash of an explosion. The film did not say much about radiation.⁵ Cities marked fallout shelters. None of this amounted to a complete plan for surviving a general nuclear war, but it did give the public something more useful than slogans and fear.

The threat soon outgrew the program. Thermonuclear weapons and intercontinental ballistic missiles reduced warning time to minutes and made mass evacuation difficult. Civil defense never received funding on the scale of the strategic forces, and it shifted from agency to agency, making it difficult to sustain a consistent long-term plan. What remained was the idea that preparing the civilian base was part of national defense, not simply a civic afterthought.

The Long Shift from Civil Defense to Emergency Management

During the 1960s and 1970s, the line between civil defense and disaster work blurred for practical reasons. Floods, hurricanes, earthquakes, industrial accidents, and concerns about nuclear power required many of the same tools: warning, evacuation, communications, emergency medicine, continuity of government, and support for state and local authorities. By the late 1970s, those functions were scattered across the executive branch, and governors wanted a single place in Washington to address them.

Reorganization Plan No. 3 of 1978 established the Federal Emergency Management Agency, and Executive Order 12127 made the plan effective on April 1, 1979. FEMA absorbed disaster and preparedness offices, including the Defense Civil Preparedness Agency. A second executive order later that year gave the agency responsibility for both emergency management and civil defense. Administratively, the merger made sense. In practice, it created a long list: hurricanes and floods arrived on a schedule the public could see, while a strategic attack on the homeland competed for attention with more immediate and visible problems.⁶

The end of the Cold War completed the shift. Congress repealed most of the Federal Civil Defense Act in 1994 and placed several remaining authorities in Title VI of the Stafford Act. In 1999, FEMA removed civil-defense regulations that it said were no longer authorized, had been covered elsewhere, or had become obsolete, and explained that at least part of the old program had merged into emergency preparedness.⁷ No single president ordered this change. Threats shifted, budgets tightened, and FEMA was told to concentrate on the disasters Americans actually experienced.

The result was an incident-driven emergency-management system, and that system has saved lives. It should be retained. But a flood or a hurricane, even a catastrophic one, is not the same problem as a campaign designed to damage several sectors at once, muddy public information, and slow the national response. Older civil defense was intended for that second problem.

Why the Question Has Returned

Geography no longer makes the homeland a sanctuary. The most serious threats may not arrive with a mushroom cloud. They can begin with access to a network, a damaged transformer, false messages aimed at the public, or the loss of a service that people assume will always be available. On February 7, 2024, CISA, the National Security Agency, and the FBI warned that Chinese state-sponsored actors associated with Volt Typhoon had been “pre-positioning” on American critical-infrastructure networks for disruptive or destructive use in a future crisis or conflict.¹

The targets described in Advisory AA24-038A were not abstract military sites. The agencies reported compromises in communications, energy, transportation, and water and wastewater systems. In some cases, the actors moved from ordinary information technology networks to operational technology and maintained access for long periods.¹ The warning was not that a national catastrophe was certain. It was that the work of preparing can be done years before the public knows a crisis has started.

This is a different technical problem from the nuclear threat of the 1950s, but the strategic implication is familiar. Modern life depends on tightly connected systems, and in many cases, those systems are privately owned. If power, communications, water, transportation, and financial services fail together, the damage will not remain inside one county or one agency. Hospitals, food distribution, 911 centers, city hall, and the movement of forces all depend on these systems. Whether essential functions can continue under degraded conditions is a national-security question, not merely an emergency-management question.

FEMA, state emergency managers, local first responders, and voluntary agencies should not be dismantled or copied. They are the country’s response system. What they are not staffed or organized to do, day after day, is plan against an adversary seeking to create disruption rather than respond to it. That planning starts from different assumptions: several systems may fail at once, information will be contested, and federal assistance may arrive late because the emergency is national rather than local.

The Citizen’s Role: Preparation Without Panic

Civil defense was never meant to be a spectator program. In the Second World War and the early Cold War, civilians served as wardens, aircraft spotters, first-aid workers, radio operators, shelter managers, and members of local defense organizations.³ The quality varied, and some of it was theater. The premise was still sound: a town with trained people, working communications, and a realistic picture of its weak points recovers faster than a town waiting for a circular from headquarters.

Public guidance is where these programs usually stumble. “Duck and Cover” is remembered as much for its limits as for its reach. After September 11, the recommendation to use “duct tape and plastic sheeting” to seal doorways against a chemical or biological attack received similar criticism, and critics called it “duct tape and cover.” Ridicule does not prove that public education is pointless. It proves that people will ignore advice that sounds theatrical, vague, or disconnected from the danger in front of them. Honest limits matter first. Government cannot promise to stop every disruption, and no household kit will solve a national problem.⁵

A narrower approach is more useful. Families need a plan for several days without dependable power, phones, or running water. Cities need warning systems people can hear, mutual-aid agreements that have been exercised, and drills that do not assume the usual roads and networks will be open. Firms and public institutions need to map their dependencies before a crisis forces them to do it. Operators of critical infrastructure need to treat logging, patching, segmentation, and manual workarounds as part of keeping the plant running, not as a separate cybersecurity chapter.¹

Sweden offers a contemporary example of a government that has made individual preparedness and civil defense explicit public responsibilities. Its guidance asks households to be able to meet their basic needs for at least a week without support from society, and treats that resilience as part of the country’s total defense. The American system cannot simply import another country’s model, but it can take the lesson: public confidence is built before the outage, by repeated practical work, not by a press conference after the lights go out.⁸

What a Modern Civil-Defense Program Would Do

A revived effort would not look like the 1950s program. It would not organize schoolchildren around one drill, and it would not sell shelter from every hazard. The test is whether the country can absorb a blow, sustain essential functions, and recover quickly enough that an adversary gains little by attacking civilian systems.

1. Energy, water, communications, transportation, health care, and finance need redundancy, segmentation, disciplined maintenance, and procedures tested when the digital layer is unavailable.¹
2. Exercises should begin with the possibility that a cyber incident, an information operation, a supply delay, and physical damage arrive together. Planning one hazard at a time prepares the country for the last storm, not for a coordinated campaign.
3. Federal and state agencies, cities, ports, hospitals, and distributors need to know, in writing, what has to keep operating during a long emergency and what can wait. Restoring a failed system is only half the problem; governing and supplying the country while the system remains broken is the other half.
4. Most of the infrastructure that matters is privately owned. Government can set standards, share intelligence, and coordinate a response, but it cannot create resilience by itself. Utilities, carriers, railroads, hospitals, and banks that actually run the country have to be part of the plan.
5. Constant catastrophe talk produces fatigue, not readiness. The public needs repeated and ordinary guidance: household preparation, a short list of trustworthy sources, local ways to help, and clear instructions not to interfere with the response.

Cold War civil defense was imperfect: underfunded, procedurally cumbersome, and at times more symbolic than capable. The logic behind it was still right. A country that prepares only for disasters that happen on their own will be late to an adversary trying to cause them. The United States does not need the bureaucracy of 1951, but it does need to treat the resilience of civilian society as part of national defense again, and pay for it.
