Trump and the Alien Enemies Act of 1798 have become intertwined in contemporary discussions about immigration policy, as this historic law has resurfaced in today’s debates over presidential power and national security. Originally enacted during a time of national insecurity and fear of foreign influence, the Alien Enemies Act has emerged as a powerful tool in modern immigration enforcement, raising profound questions about its application and implications for immigrants. Despite being over two centuries old, the Act has recently been invoked in ways that directly affect immigrants in modern America, creating a striking juxtaposition of 18th-century legal frameworks with 21st-century immigration challenges. As the oldest surviving component of the controversial Alien and Sedition Acts, this legislation gives the president extraordinary powers to detain and deport non-citizens from countries with which the United States is at war, powers that are now being reinterpreted and applied in unprecedented ways.
The Historical and Legislative Context: Origins of the Alien and Sedition Acts
The Alien Enemies Act was one of four laws collectively known as the Alien and Sedition Acts, passed by the Federalist-controlled Congress and signed into law by President John Adams in 17982. These laws emerged during a period of significant international tension, particularly between the United States and Revolutionary France2. The United States had recently emerged from the American Revolution and was navigating its newfound independence in a world dominated by European powers6.
The political climate of the late 18th century was characterized by deep polarization between the Federalists, led by Adams and Alexander Hamilton, who leaned toward Britain, and the Democratic-Republicans, led by Thomas Jefferson and James Madison, who favored maintaining the historic alliance with France6. This political division was exacerbated by fears of foreign influence and internal dissent, creating a climate of suspicion toward immigrants, particularly those from France.

The XYZ Affair and Rising Tensions
In 1797, a diplomatic controversy known as the XYZ Affair heightened tensions between the United States and France. French diplomats demanded bribes from American envoys to negotiate disputes, leading to public outrage in the United States and calls for military preparedness6. This incident precipitated an undeclared naval war with France, often referred to as the Quasi-War (1798-1800)2.
Against this backdrop of international conflict and domestic political division, the Federalists saw an opportunity to consolidate power and suppress political opposition, which they associated with Democratic-Republican sympathies for France6. The result was the passage of the four laws that constituted the Alien and Sedition Acts.
The Four Acts and Their Purposes
The Alien and Sedition Acts consisted of four distinct laws with different purposes but a common theme of restricting foreign influence and political dissent:
- The Naturalization Act, which increased the residency requirement for citizenship from 5 to 14 years, making it more difficult for immigrants to become citizens and vote2.
- The Alien Friends Act, which empowered the president to deport any non-citizen deemed dangerous to the peace and safety of the United States2.
- The Alien Enemies Act, which authorized the president to apprehend, restrain, secure, and remove non-citizens from countries with which the United States was at war23.
- The Sedition Act, which criminalized making false statements critical of the federal government2.
While the Alien Friends Act and the Sedition Act were controversial and expired in 1800 and 1801 respectively, and the Naturalization Act was repealed in 1802, the Alien Enemies Act has remained in force to this day3. It is the only surviving component of the original four acts, a testament to its perceived utility during times of war and national emergency.
Legal Framework and Historical Application
Powers Granted by the Alien Enemies Act
The Alien Enemies Act grants the president broad powers during times of declared war or invasion. Specifically, it authorizes the president to apprehend, restrain, secure, and remove all natives, citizens, denizens, or subjects of a hostile nation or government who are 14 years old and older and not naturalized U.S. citizens1.
The act effectively allows the executive branch to bypass normal immigration proceedings and expedite the removal of individuals based solely on their nationality and lack of U.S. citizenship1. This extraordinary power is premised on the notion that during wartime, nationals of enemy states may pose inherent security risks regardless of their individual actions or intentions.
As explained by Morgan Bailey, former deputy chief of staff at U.S. Immigration and Customs Enforcement during Trump’s first term: “Utilizing the Alien Enemies Act streamlines the process, eliminating the requirement for individuals to present their case before an immigration judge. Instead, deportation could occur solely based on national affiliation”1.

Historical Applications
Despite its longevity, the Alien Enemies Act has been invoked relatively rarely in American history. The most significant application occurred during World War II, when approximately 31,000 individuals of predominantly Japanese, Italian, and German descent were interned under its authority1. This period represents one of the darkest chapters in American immigration and civil liberties history, with many innocent people detained solely based on their national origin.
Prior to World War II, the act was also used during World War I to detain and deport Germans and other nationals of Central Powers countries. These historical applications demonstrate how the act has typically been employed during formally declared wars against nation-states, consistent with its original intent.
Legal Interpretation and Limitations
A critical aspect of the Alien Enemies Act is that it traditionally requires a formal declaration of war by Congress to be invoked1. This limitation has historically constrained its use to periods of officially declared warfare, of which there have been relatively few in American history. The last formal declaration of war by the United States occurred during World War II.
Over time, legal scholars and courts have debated the scope and constitutionality of the act. While the Supreme Court has generally deferred to executive authority in matters of national security during wartime, questions remain about the application of the act in modern contexts where formal declarations of war are rare and conflicts are often against non-state actors rather than sovereign nations.
The Act in the Modern Era
Dormancy and Revival
For decades following World War II, the Alien Enemies Act remained largely dormant. The nature of conflict changed, with the United States engaging in military actions without formal declarations of war, such as in Korea, Vietnam, and later conflicts in the Middle East. Without declared wars against nation-states, the traditional triggering mechanism for the act was absent.
However, in recent years, there has been renewed interest in the act as a potential tool for immigration enforcement. This revival corresponds with increasing political focus on immigration control and national security concerns related to non-citizen populations.
Trump’s Campaign Promises and Policy Proposals
Former President Trump brought the Alien Enemies Act back into public discourse during his political campaigns. He consistently promised to “invoke the Alien Enemies Act to dismantle every migrant criminal network” as part of his platform on immigration enforcement13. These statements represented a novel interpretation of the act, suggesting it could be applied to criminal organizations rather than nationals of enemy states during declared wars.
At campaign rallies, Trump emphasized the act’s “powerful” nature, telling supporters: “Think of that, 1798. Oh, it’s a powerful act. You couldn’t pass something like that today”3. This rhetoric highlighted his view of the act as an extraordinary tool for immigration enforcement that circumvents normal legislative constraints.
The Republican Party incorporated the Alien Enemies Act into its official 2024 platform, stating it would invoke the law to “remove all known or suspected gang members, drug dealers, or cartel members from the United States, ending the scourge of Illegal Alien gang violence once and for all”3. This formal adoption signaled a significant shift in how political leaders envisioned using this historical wartime power.

Reinterpreting War and Enemies
This modern revival of interest in the Alien Enemies Act has involved reinterpreting key concepts within the law. Proponents have argued that mass illegal immigration constitutes an “invasion” that could trigger the act’s provisions, and that transnational criminal organizations like drug cartels and gangs could be classified as “enemies” even without a formal declaration of war1.
Legal experts have expressed skepticism about these interpretations. George Fishman, a senior legal fellow at the conservative Center for Immigration Studies and former deputy general counsel at the Department of Homeland Security during the Trump administration, acknowledged that “it will be challenging to persuade federal courts to endorse its application,” noting that “federal courts have historically not recognized mass illegal immigration as fitting the constitutional definition of invasion”1.
Nonetheless, Fishman suggested that “the concepts of invasion and predatory incursion could be reasonably debated in court”1, indicating that there may be legal pathways to justify a broader application of the act than its historical usage would suggest.
Recent Developments (2025)
Trump’s Invocation of the Act Against Tren de Aragua
In a significant development, President Trump has recently (March 2025) invoked the Alien Enemies Act, targeting members of a Venezuelan gang called Tren de Aragua for expedited deportation1. This marks only the fourth time in U.S. history that a president has activated this act, and the first instance since World War II1.
The presidential directive specifically permits the swift removal of all Venezuelan nationals aged 14 and older identified as members of this group, provided they are neither U.S. citizens nor lawful permanent residents1. According to the presidential proclamation, such individuals “are subject to apprehension, detention, and removal as Alien Enemies”5.
The proclamation declares that “No Alien Enemy described in section 1 of this proclamation shall enter, attempt to enter, or be found within any territory subject to the jurisdiction of the United States. Any such Alien Enemy who enters, attempts to enter, or is found within such territory shall be immediately apprehended and detained until removed from the United States”5.
This action followed a January executive order that categorized Tren de Aragua as a foreign terrorist organization, which the administration argued facilitated the expulsion of its members from U.S. soil under the Alien Enemies Act1. The administration has dubbed this initiative “Operation Aurora,” named after a Colorado town that Trump claims has been taken over by Venezuelan gangs, an assertion disputed by residents and local officials3.
Legal Challenges and Judicial Response
Shortly after Trump’s announcement, U.S. District Court Chief Judge James Boasberg issued an injunction preventing the administration from utilizing this wartime authority for deportations, instructing that any planes already in flight be redirected14. Earlier that day, Judge Boasberg had ruled in a case brought forth by the American Civil Liberties Union and Democracy Forward prohibiting the deportation of five Venezuelan men for a period of 14 days14.
The lawsuit, J.G.G. v. Trump, challenges the president’s invocation of the act as unlawful and unprecedented4. The temporary restraining order specifically protects the individual plaintiffs in the lawsuit from removal for 14 days, with hearings scheduled to determine whether the order should be broadened to cover everyone potentially affected by the act4.
This swift judicial response demonstrates the tension between executive authority and judicial review in matters of immigration enforcement and national security. The courts are now tasked with determining whether the President’s novel application of this historical wartime power falls within legal boundaries.
Legal and Constitutional Questions Raised
The administration’s use of the Alien Enemies Act raises several critical legal questions. First, there is the question of whether the act can be invoked without a formal declaration of war by Congress. Traditionally, the act has been limited to periods of declared war against sovereign nations, not against criminal organizations or in response to immigration concerns1.
Second, there are questions about the scope of presidential authority under the act. The expedited removal process allowed by this act means that individuals affected by the president’s declaration will not undergo the standard immigration court proceedings, nor will they have the opportunity to seek asylum1. This bypassing of established due process protections raises significant constitutional concerns.
Third, there are concerns about the potential for discriminatory application. Critics have noted that “there’s nothing in the law that confines it to undocumented individuals or those who have committed crimes,” suggesting that the power could be used broadly against nationals of designated countries regardless of their immigration status or personal conduct1.

Implications for Immigrant Communities
Expanded Deportation Powers
The invocation of the Alien Enemies Act represents a significant expansion of executive deportation powers. Under normal immigration proceedings, non-citizens generally have rights to hearings before immigration judges, opportunities to seek asylum if they fear persecution in their home countries, and various procedural protections designed to ensure fair treatment.
The Alien Enemies Act effectively circumvents these protections. As Katherine Yon Ebright, a legal advisor at the Brennan Center for Justice, observed: “This aligns with the notion that it is a wartime power rather than an immigration authority”1. The distinction is crucial because wartime powers traditionally operate with fewer constraints than administrative immigration procedures.
This expedited process raises serious concerns about mistaken identifications, lack of opportunity to present evidence of lawful status or asylum claims, and the potential for abuse of power. Without individualized assessments, people may be deported based solely on group affiliation or nationality, regardless of their personal circumstances or potential claims for protection.
Fear and Uncertainty in Immigrant Communities
The invocation of this rarely-used wartime power has created fear and uncertainty in immigrant communities, particularly among those from countries that might be targeted under the act. Even immigrants with lawful status may worry about being swept up in enforcement actions if they share a nationality with targeted groups.
The inclusion of minors as young as 14 in the recent presidential directive adds another layer of concern, as it potentially subjects young people to expedited removal without the special protections normally afforded to minors in immigration proceedings1. This aspect of the directive is particularly troubling from a humanitarian perspective, as it could result in the deportation of children without adequate consideration of their best interests or potential vulnerabilities.
Broader Implications for Immigration Policy
The use of the Alien Enemies Act represents a significant shift in immigration enforcement philosophy, prioritizing expedited removal based on group affiliation over individualized assessments. This approach treats immigration primarily as a national security issue rather than a civil or humanitarian matter.
If upheld by courts and continued as policy, this shift could fundamentally alter the nature of immigration enforcement in the United States, moving away from case-by-case adjudication toward more categorical approaches based on nationality and alleged group affiliations. Such a shift would have profound implications for due process, family unity, and the treatment of vulnerable populations within the immigration system.
The Human Impact of Extraordinary Immigration Powers
Effects on Individuals and Families
Beyond the legal and constitutional questions, the invocation of the Alien Enemies Act has profound human consequences. When individuals are detained and deported without standard immigration proceedings, families can be separated with little warning or opportunity to make arrangements. Children may be left without parents, spouses separated, and communities disrupted in ways that create lasting trauma and hardship.
The psychological impact of living under the threat of such extraordinary enforcement measures creates a climate of fear that affects daily life, economic participation, and community integration. Even those not directly targeted may withdraw from public life, avoid seeking necessary services like healthcare or education, or live in constant anxiety about their status and safety.
For individuals who might qualify for asylum or other forms of relief under normal immigration proceedings, the expedited removal process under the Alien Enemies Act could result in return to countries where they face persecution, violence, or extreme hardship. This outcome would contravene not only U.S. asylum law but also international refugee protection principles.
Advocacy and Community Response
In response to the invocation of the Alien Enemies Act, immigrant advocacy organizations have mobilized to provide legal support, community education, and policy advocacy. Groups like the American Civil Liberties Union have filed legal challenges to prevent deportations under the act4, while community-based organizations work to support affected individuals and families.
These advocacy efforts highlight the tension between enforcement-focused immigration policies and humanitarian concerns about family unity, community stability, and proportional consequences for immigration violations. They also reflect a broader debate about American values and identity in relation to immigration and the treatment of non-citizens.
International Comparisons and Human Rights Considerations
International Law and Human Rights Standards
The United States’ use of the Alien Enemies Act raises questions about compliance with international human rights standards. The United Nations Refugee Convention, to which the United States is a signatory, prohibits the return of individuals to countries where they face persecution (the principle of non-refoulement). The expedited removal process under the Alien Enemies Act potentially bypasses asylum screenings that would identify such risks.
Similarly, the International Covenant on Civil and Political Rights, which the United States has ratified, guarantees certain due process protections and prohibits arbitrary detention. The detention and removal powers under the Alien Enemies Act may conflict with these international obligations, particularly when applied to individuals with no connection to hostilities beyond their nationality.
Comparative Approaches in Other Democracies
Other democratic nations face similar challenges balancing national security with immigrant rights and due process. Many countries have emergency powers that can be invoked during wartime, but few have maintained such broad authority to detain and deport non-citizens based solely on nationality as provided by the Alien Enemies Act.
In recent years, countries like the United Kingdom, France, and Germany have grappled with security concerns related to immigration, particularly regarding terrorism. However, most have maintained stronger judicial oversight and individualized assessment requirements than what the Alien Enemies Act permits, reflecting contemporary human rights standards and democratic values.
Historical Parallels and Lessons
The World War II Precedent
The last major application of the Alien Enemies Act during World War II resulted in the internment of approximately 31,000 people of Japanese, German, and Italian descent1. This episode, along with the broader Japanese American internment conducted under different legal authorities, has been widely recognized as a dark chapter in American history that prioritized unfounded security fears over civil liberties and human rights.
The historical parallels raise important questions about whether the current use of the act reflects lessons learned from past mistakes or represents a concerning repetition of history. The targeting of specific nationalities without individualized assessments of threat echoes problematic aspects of the World War II internments that many historians and legal scholars now view as violations of civil liberties and equal protection principles.
Evolution of National Security Powers
The use of the Alien Enemies Act also reflects the broader evolution of national security powers in American governance. Since the September 11, 2001 terrorist attacks, there has been an expansion of executive authority in the name of national security, including measures like the USA PATRIOT Act and various executive orders related to immigration enforcement and surveillance.
The invocation of this centuries-old act alongside modern security measures demonstrates both the continuity of certain security concerns throughout American history and the adaptability of legal frameworks to address new perceived threats. It also highlights ongoing tensions between security imperatives and civil liberties protections in American governance.
The Future of the Alien Enemies Act
Potential Legislative Reforms
Given the controversy surrounding the Alien Enemies Act and its potential for broad application, there may be calls for legislative reform or repeal. Congress has the authority to modify or abolish the act, as it did with the other components of the original Alien and Sedition Acts.
Potential reforms could include adding judicial review requirements, limiting the act’s application to formally declared wars, establishing clearer criteria for who can be detained or deported under its authority, or providing greater procedural protections for affected individuals. Such reforms would aim to preserve legitimate national security tools while preventing potential abuses of power.
Ongoing Judicial Interpretation
The current legal challenges to the act’s implementation will likely shape its future application. If courts uphold broad presidential authority under the act, it could become a more frequently used tool in immigration enforcement. Conversely, if courts impose significant limitations, the act may return to relative obscurity or be confined to traditional wartime applications.
The Supreme Court could eventually be called upon to determine the act’s constitutionality in the modern context, particularly regarding due process requirements and the definition of “war” and “enemies” for purposes of the act. Such a ruling would have far-reaching implications for executive power, immigration enforcement, and the rights of non-citizens in the United States.
Policy Implications and Recommendations
From a policy perspective, reliance on the Alien Enemies Act represents a significant shift toward treating immigration as primarily a national security issue rather than a civil or humanitarian matter. This approach prioritizes expedited enforcement over individualized assessment and due process.
A more balanced approach might maintain strong immigration enforcement while preserving case-by-case evaluation, judicial oversight, and protection for vulnerable populations such as asylum seekers. This would require more resources for immigration courts and asylum officers but would better align with constitutional values and international human rights obligations.
Conclusion
The Alien Enemies Act of 1798 stands as one of the oldest active federal laws in the United States, a living connection to the early republic’s struggles with national security, foreign influence, and the boundaries of federal power. Its recent revival in immigration enforcement contexts demonstrates both the remarkable adaptability of American legal frameworks and the persistent tensions between security imperatives and civil liberties.
The act’s journey from an 18th-century wartime measure to a 21st-century deportation mechanism illustrates the enduring challenge of balancing legitimate security concerns with humanitarian values and due process protections. Its current application against members of a Venezuelan gang represents a novel interpretation that extends its reach beyond traditional wartime contexts to address perceived threats from transnational criminal organizations.
As the United States continues to navigate complex immigration challenges, the debate over the Alien Enemies Act invites reflection on fundamental questions about national identity, constitutional values, and the treatment of non-citizens. It reminds us that the balance between security and liberty is not merely a theoretical concern but a practical matter with real consequences for real people families separated, lives disrupted, and communities divided.
The resolution of current legal challenges to the act’s application will establish important precedents for future immigration enforcement and executive power. Whatever the outcome, it is essential that policies reflect not only security needs but also America’s enduring commitment to due process, equal protection, and human dignity.
In a nation defined by both the rule of law and a heritage of immigration, finding this balance is not merely a legal necessity but a moral imperative. The story of the Alien Enemies Act—from its 18th-century origins to its 21st-century applications—is ultimately a story about America itself, its fears and aspirations, its powers and limitations, and its ongoing effort to form a more perfect union that provides both security and justice for all within its borders.
