Civil Liberties during Wartime: Internment, Surveillance

This article examines the tension between civil liberties and national security during wartime, focusing on historical instances of internment and surveillance, legal frameworks, and contemporary implications for individual rights.


Civil liberties are fundamental rights and freedoms protected by law, often enshrined in a nation's constitution. However, during wartime, these liberties can be significantly curtailed in the name of national security. This article explores the complex interplay between civil liberties and national security, focusing on internment and surveillance during wartime. We will delve into historical precedents, legal frameworks, and contemporary implications, providing a comprehensive understanding of this critical issue.

Historical Context

Japanese-American Incarceration During World War II

During World War II, the U.S. government forcibly relocated and incarcerated approximately 120,000 Japanese Americans, two-thirds of whom were U.S. citizens. This action was justified by the government as a necessary measure to prevent espionage and sabotage following the attack on Pearl Harbor.

Executive Order 9066

On February 19, 1942, President Franklin D. Roosevelt signed Executive Order 9066, which authorized the Secretary of War to designate military areas from which any or all persons could be excluded. This order laid the groundwork for the mass internment of Japanese Americans.

The internment of Japanese Americans was challenged in the landmark Supreme Court case Korematsu v. United States. Fred Korematsu, a Japanese American citizen, defied the internment order and was subsequently arrested and convicted. Korematsu appealed his conviction, arguing that the internment order violated his constitutional rights.

Supreme Court Decision

In a controversial decision, the Supreme Court upheld Korematsu's conviction, ruling that the need to protect against espionage outweighed Korematsu's individual rights. The Court's decision has been widely criticized for its endorsement of racial discrimination under the guise of national security.

Civil Liberties Act of 1988

In 1988, the U.S. government formally acknowledged the injustice of the internment of Japanese Americans through the Civil Liberties Act of 1988. This legislation provided a formal apology and monetary reparations to surviving internees.

Constitutional Protections

The U.S. Constitution provides several protections for civil liberties, including the Bill of Rights. Key amendments relevant to wartime internment and surveillance include:

  • First Amendment: Protects freedom of speech, religion, and assembly.
  • Fourth Amendment: Protects against unreasonable searches and seizures.
  • Fifth Amendment: Guarantees due process of law.
  • Fourteenth Amendment: Provides equal protection under the law.

War Powers and National Security

The U.S. government has broad powers to ensure national security during wartime. These powers are derived from the Constitution, statutes, and judicial decisions. Key legal authorities include:

  • Article II of the Constitution: Grants the President authority as Commander-in-Chief of the armed forces.
  • War Powers Resolution of 1973: Limits the President's power to engage in military action without congressional approval.
  • USA PATRIOT Act: Enacted after the September 11 attacks, this law expanded the government's surveillance and investigative powers.


Historical Precedents

World War I

During World War I, the U.S. government targeted German Americans, leading to the internment of thousands of individuals of German descent. This action was justified by concerns over loyalty and espionage.

World War II

The internment of Japanese Americans during World War II is the most well-known example of wartime internment. Other groups, including Italian Americans and German Americans, were also subjected to internment, though on a smaller scale.

Military Necessity

The primary legal justification for internment during wartime is military necessity. This concept allows the government to take extraordinary measures to protect national security, even if it means curtailing individual liberties.

Judicial Review

Courts have generally been deferential to the government's claims of military necessity during wartime. However, this deference has been criticized for allowing the government to infringe on civil liberties without sufficient oversight.


Historical Context

World War I and II

During both World Wars, the U.S. government engaged in extensive surveillance of individuals and groups suspected of disloyalty. This included monitoring communications, infiltrating organizations, and conducting warrantless searches.

Cold War

The Cold War era saw the expansion of government surveillance programs, particularly targeting suspected communists and other perceived threats to national security. The FBI's COINTELPRO program, for example, involved extensive surveillance and infiltration of civil rights organizations, anti-war groups, and other activist movements.

Foreign Intelligence Surveillance Act (FISA)

Enacted in 1978, FISA established procedures for the surveillance and collection of foreign intelligence information. The law created the Foreign Intelligence Surveillance Court (FISC) to oversee requests for surveillance warrants.

The USA PATRIOT Act, passed in response to the September 11 attacks, significantly expanded the government's surveillance powers. Key provisions include:

  • Section 215: Allows the government to obtain business records and other tangible items for foreign intelligence and terrorism investigations.
  • Section 702: Authorizes the collection of electronic communications of non-U.S. persons located outside the United States.

Judicial Oversight

Foreign Intelligence Surveillance Court (FISC)

The FISC is responsible for reviewing and approving surveillance requests under FISA. Critics argue that the court operates with limited transparency and provides insufficient oversight of government surveillance activities.

Supreme Court Cases

Several Supreme Court cases have addressed the balance between national security and civil liberties in the context of surveillance. Key cases include:

  • Katz v. United States: Established that the Fourth Amendment protects individuals' reasonable expectation of privacy.
  • Clapper v. Amnesty International USA: Addressed the standing of individuals to challenge government surveillance programs.

Contemporary Implications

Post-9/11 Era

The September 11 attacks led to a significant expansion of government surveillance and security measures. The USA PATRIOT Act and subsequent legislation have raised concerns about the erosion of civil liberties in the name of national security.

Technological Advancements

Advances in technology have transformed the landscape of surveillance. The government's ability to monitor communications, track movements, and collect data has increased exponentially, raising new challenges for protecting civil liberties.

Ongoing Debates

Balancing Security and Liberty

The tension between national security and civil liberties remains a contentious issue. Advocates for civil liberties argue that excessive government surveillance and internment measures undermine the fundamental rights and freedoms that define democratic societies.

Efforts to reform surveillance laws and enhance oversight continue. Proposed reforms include increasing transparency, strengthening judicial oversight, and ensuring that surveillance measures are narrowly tailored to protect civil liberties.


The history of civil liberties during wartime, particularly in the context of internment and surveillance, underscores the delicate balance between national security and individual rights. While the government has a legitimate interest in protecting national security, it must also safeguard the fundamental freedoms that are the cornerstone of a democratic society. Ongoing vigilance, legal reforms, and public awareness are essential to ensure that civil liberties are not unduly sacrificed in the name of security.
