“Until Trump took office in January, the AEA had been invoked only three times in 226 years: during the War of 1812, World War I, and World War II. All of those situations fell into the “declared war” category. The AEA has never previously been invoked in response to a putative “invasion or predatory incursion” outside the context of a declared war. That is the threat Trump cites to justify peremptorily deporting suspected members of the Venezuelan gang Tren de Aragua.”

“Trump does not claim to be at war with Venezuela. Nor does he claim that the Venezuelan government has mounted an “invasion or predatory incursion against the territory of the United States.” And a criminal organization, even one that has corrupted or “infiltrated” a foreign government, is not a “hostile nation or government” as those terms are ordinarily understood.
Nor does Trump’s understanding of “invasion or predatory incursion” make sense in the context of the AEA. “As the Supreme Court and past presidents have acknowledged, the Alien Enemies Act is a wartime authority enacted and implemented under the war power,” Katherine Yon Ebright, a lawyer at the Brennan Center for Justice who specializes in national security issues, explained last fall. “When the Fifth Congress passed the law and the Wilson administration defended it in court during World War I, they did so on the understanding that noncitizens with connections to a foreign belligerent could be ‘treated as prisoners of war’ under the ‘rules of war under the law of nations.’ In the Constitution and other late-1700s statutes, the term invasion is used literally, typically to refer to large-scale attacks. The term predatory incursion is also used literally in writings of that period to refer to slightly smaller attacks like the 1781 Raid on Richmond led by American defector Benedict Arnold.””

“”There is a lot of law about what constitutes a foreign government,” Gelernt told Boasberg. “And I don’t think the United States recognizes [Tren de Aragua] as a foreign government. They recognize Venezuela as a foreign government. I think that’s thehistoric understanding of the statute.”
Gerlent also questioned the government’s definition of “invasion or predatory incursion”: “We think the Court certainly can review whether immigration constitutes some kind of invasion….We know of no historical precedent that would suggest that straight migration or noncitizens coming and committing crimes constitutes an invasion within the meaning of the statute or the Constitution.””
