President Trump’s decision to send U.S. forces into Venezuela to capture President Nicolás Maduro and his wife and return them to the U.S. to face drug charges elicited condemnation from legal experts and other critics who argued that the operation — conducted without congressional or United Nations approval — clearly violated U.S. and international law.
Such criticism came from Democratic leaders, international allies and adversaries including Mexico, France, China and Russia, United Nations Secretary-General Antonio Guterres and experts on international law and wartime powers.
“Nicolás Maduro was a thug and an illegitimate leader of Venezuela, terrorizing and oppressing its people for far too long and forcing many to leave the country. But starting a war to remove Maduro doesn’t just continue Donald Trump’s trampling of the Constitution, it further erodes America’s standing on the world stage and risks our adversaries mirroring this brazen illegal escalation,” Sen. Adam Schiff (D-Calif.) wrote on X.
A U.N. spokesman said Guterres was “deeply alarmed” by the U.S. operation and “deeply concerned that the rules of international law have not been respected.”
China’s foreign ministry said “such hegemonic acts of the U.S. seriously violate international law and Venezuela’s sovereignty,” while France’s foreign minister said the U.S. operation “contravenes the principle of the non-use of force that underpins international law.”
Republicans largely backed the president, with both House Speaker Mike Johnson (R-La.) and Senate Majority Leader John Thune (R-S.D.) defending the operation as “decisive” and legally justified. However, other Republicans questioned Trump’s authority to act unilaterally, and raised similar concerns as Schiff about other world leaders citing Trump’s actions to justify their own aggression into neighboring nations.
Rep. Don Bacon (R-Neb.) defended Trump’s actions as “great for the future of Venezuelans and the region,” but said he was concerned that “Russia will use this to justify their illegal and barbaric military actions against Ukraine, or China to justify an invasion of Taiwan.”
Trump defended the operation as a legitimate law enforcement action necessary to combat threats to the U.S. from Maduro, whom he accused of sending violent gang members and deadly drugs across the U.S. border on a regular basis.
“The illegitimate dictator Maduro was the kingpin of a vast criminal network responsible for trafficking colossal amounts of deadly and illicit drugs into the United States,” Trump said at a news conference. “As alleged in the indictment, he personally oversaw the vicious cartel known as Cartel de los Soles, which flooded our nation with lethal poison responsible for the deaths of countless Americans.”
However, Trump also made no secret of his interest in Venezuela’s oil. He said U.S. officials would be running Venezuela for the foreseeable future and ensuring that the nation’s oil infrastructure is rebuilt — to return wealth to the Venezuelan people, but also to repay U.S. businesses that lost money when Maduro took over the industry.
Atty. Gen. Pam Bondi announced that Maduro, who had previously been indicted in the U.S. in 2020, is now the subject of a superseding indictment charging him, his wife and several others with narco-terrorism conspiracy, cocaine importation conspiracy, possession of machine guns and destructive devices and conspiracy to possess such weapons and devices.
“They will soon face the full wrath of American justice on American soil in American courts,” Bondi wrote on X.
Secretary of State Marco Rubio also framed the operation as a law enforcement effort, and defended the lack of advance notice to Congress.
“At its core, this was an arrest of two indicted fugitives of American justice, and the Department of War supported the Department of Justice in that job,” Rubio said. “It’s just not the kind of mission that you can pre-notify, because it endangers the mission.”
Trump said Congress could not be notified in advance because “Congress will leak, and we don’t want leakers.”
Michael Schmitt, an international law professor at the University of Reading in the United Kingdom and a professor emeritus of international law at the U.S. Naval War College, said Trump’s actions were a “clear violation” of international law.
He said the U.S. had no authority from the U.N. Security Council to conduct military operations in Venezuela, nor any legitimate justification to act in self-defense against an armed attack — which drug trafficking does not amount to.
Schmitt said the operation in Venezuela went far beyond a normal law enforcement action. But even if it were just a law enforcement action, he said, the U.S. would still lack legal authority under international law to engage in such activity on Venezuelan soil without the express permission of Venezuelan authorities — which it did not have.
“International law is clear. Without consent, you cannot engage in investigations or arrest or seizure of criminal property on another state’s territory,” he said. “That’s a violation of that state’s sovereignty.”
Because the operation was illegitimate from the start, the resulting occupation and interference in Venezuela’s oil industry are also unlawful, Schmitt said — regardless of whether the country’s nationalizing of U.S.-tied oil infrastructure was also unlawful, as some experts believe it was.
“That unlawfulness — of seizing U.S. business interests, nationalizing them, in a way that was not in accordance with the required procedures — is not a basis for using force,” Schmitt said.
Matthew Waxman, chair of the National Security Law Program at Columbia Law School, said that in the days ahead, he expects the Trump administration to try to justify its actions not just as a law enforcement operation, but “as part of a larger campaign to defend the United States against what it has characterized as an attack or invasion by Maduro-linked drug cartels.”
“All modern presidents have claimed broad constitutional power to use military force without congressional authorization, but that is always hotly contested. We’ll see if there’s much pushback in Congress in this case, which will probably depend a lot on how things now play out in Venezuela,” Waxman said. “Look at what happened last year in Iran: The president claimed the power to bomb nuclear program infrastructure, and when the operation didn’t escalate, congressional opponents backed off.”
Already on Saturday, some members of Congress were softening their initial skepticism.
Within hours of posting on X that he was looking forward “to learning what, if anything, might constitutionally justify this action in the absence of a declaration of war or authorization for the use of military force,” Sen. Mike Lee (R-Utah) had posted again, saying Rubio told him that the military action was “to protect and defend those executing the arrest warrant” for Maduro.
Such action “likely falls within the president’s inherent authority under Article II of the Constitution to protect U.S. personnel from an actual or imminent attack,” Lee added.
Others remained more skeptical.
Rep. Thomas Massie (R-Ky.) said Trump’s remarks about taking over the country and controlling its oil reserves did not seem “the least bit consistent” with Bondi’s characterization of the operation as a law enforcement effort.
