Alien Enemies Act: Could Trump Revive a WWII-Era Tool? (Answer: Yes)
Washington, D.C. — In a move that could reshape immigration policy, the Trump administration is reportedly considering the use of the Alien Enemies Act of 1798 as a legal mechanism to deport migrants. This obscure piece of legislation, enacted during the early years of the United States, grants the president broad authority to detain and remove non-citizens deemed a threat during times of war or national emergency.
While rarely invoked in modern times, its potential revival has sparked debate among legal scholars, policymakers, and immigrant rights advocates.
The Alien Enemies Act was originally signed into law by President John Adams as part of a series of measures known as the Alien and Sedition Acts, aimed at addressing perceived threats from foreign nationals amid tensions with France. The law allows the president to apprehend, restrain, and deport any non-citizen from a country with which the U.S. is at war, without requiring congressional approval.

Its most notable use came during World War II, when President Franklin D. Roosevelt invoked it to authorize the internment of over 120,000 Japanese Americans, a decision widely regarded today as a grave violation of civil liberties.
Sources close to the Trump transition team suggest that the administration may interpret the act’s language broadly, potentially applying it to undocumented migrants or individuals from nations deemed hostile, even in the absence of a formal declaration of war. This approach aligns with President Donald Trump’s campaign promises to prioritize border security and expedite deportations. During his first term, Trump implemented policies such as the “Remain in Mexico” program and family separations at the border, signaling a hardline stance on immigration that could intensify in his second term.
Legal experts are divided on the feasibility of this strategy.
Supporters argue that the act’s text provides clear presidential authority, especially if tied to national security concerns like drug trafficking or terrorism. “The language is intentionally broad,” said Professor Michael Carter, a constitutional law scholar at Georgetown University. “In theory, the administration could designate certain migrant groups as threats under a national emergency framework and move forward with deportations.”
Critics, however, caution that such an application would face significant legal and ethical challenges.
The American Civil Liberties Union (ACLU) has already signaled its intent to oppose any use of the act, citing its historical misuse. “This law was last used to justify one of the darkest chapters in American history,” said ACLU attorney Sarah Nguyen. “Reviving it to target vulnerable populations would almost certainly violate due process and international human rights standards.” Courts could also intervene, as they did during Trump’s first term when federal judges blocked portions of his travel ban targeting Muslim-majority countries.
The political context adds another layer of complexity.
With Republicans set to control both chambers of Congress in 2025, the administration may face less legislative resistance to its immigration agenda. However, public opinion remains polarized. A recent Gallup poll found that 54% of Americans support stricter immigration enforcement, while 41% favor expanding protections for undocumented migrants. Any move to invoke the Alien Enemies Act could reignite protests like those seen during Trump’s first term, when thousands took to the streets over immigration policies.
Historical precedent offers a mixed picture.
Beyond World War II, the act was used sparingly—once during the War of 1812 to detain British nationals and again in World War I against German Americans. Each instance occurred during a declared war, a condition absent today. To bridge this gap, the Trump administration might lean on existing national emergency declarations, such as those related to border security, though this would likely trigger lawsuits questioning the act’s scope.
Internationally, the move could strain diplomatic relations, particularly with Mexico and Central American countries, which have borne the brunt of U.S. deportation efforts. Mexican Foreign Minister Juan Morales expressed concern in a recent statement, urging dialogue over unilateral action. “We respect U.S. sovereignty but expect mutual cooperation on migration issues,” he said.
As the administration prepares to take office on January 20, 2025, the potential use of the Alien Enemies Act remains speculative but plausible. Observers say it would reflect a continuation of Trump’s aggressive approach to immigration, testing the limits of executive power in a deeply divided nation. For now, the debate simmers as stakeholders await concrete policy announcements.
