GOP Resistance Complicates Trump’s Military Calculus on Cuba

Cuban President Miguel Díaz-Canel warned Monday that any U.S. military strike on Cuba "would trigger a bloodbath with incalculable consequences," escalating an already charged exchange between Havana and Washington as the Trump administration signals it will not accept the status quo ^[1][2]. The warning came hours after Axios reported that U.S. intelligence assessments concluded Cuba had acquired more than 300 military drones, sourced from Russia and Iran, and that Cuban officials had discussed contingency plans to target the U.S. naval base at Guantánamo Bay and military vessels near Key West, Fla. ^[1][4]. U.S. officials cited by that report said no imminent attack was expected, but characterized the buildup as a "growing threat" ^[5][6].

The legal architecture supporting the administration's pressure campaign rests on Executive Order 14380, signed Jan. 29, 2026, in which President Trump invoked the International Emergency Economic Powers Act (50 U.S.C. §§ 1701 et seq.) and the National Emergencies Act (50 U.S.C. §§ 1601 et seq.) to declare Cuba "an unusual and extraordinary threat" to U.S. national security and foreign policy ^[16][12]. That declaration authorized a tariff framework targeting third countries that supply oil to Cuba, which the White House used to impose a fuel blockade that has, by independent accounts, driven the island to near-total power collapse ^[11][19]. On Monday, the administration compounded that pressure with a new executive order expanding sanctions under IEEPA to cover individuals and entities that support Cuba's security apparatus, authorized by the Secretaries of State and Treasury ^[9][10]. Secretary of State Marco Rubio announced the action and said "additional sanctions actions can be expected in the following days and weeks" ^[3].

The administration's coercive diplomacy track runs alongside its escalatory rhetoric. CIA Director John Ratcliffe traveled to Havana on May 15, in what CNBC reported was likely only the second visit by a CIA director to the island since Cuba's 1959 revolution ^[20]. Ratcliffe met with Interior Minister Lázaro Álvarez Casas, the head of Cuban intelligence services, and Raúl Guillermo Rodríguez Castro, the grandson of former President Raúl Castro. A CIA official confirmed Ratcliffe was there "to personally deliver President Donald Trump's message that the United States is prepared to seriously engage on economic and security issues, but only if Cuba makes fundamental changes." The talks also addressed intelligence cooperation and Cuba's role as a haven for U.S. adversaries in the Western Hemisphere ^[19]. No agreement was announced.

Despite that messaging, the administration faces measurable resistance within its own coalition over military action specifically. Senate Majority Leader John Thune of South Dakota, asked last week by The Hill about a potential U.S. operation to unseat Cuba's government, identified Iran as the priority [POLITICO]. "I'd love to see regime change, we all would, in Cuba," Thune said, adding that it might come through "force of events" [POLITICO]. Steve Bannon, in a text to POLITICO, invoked President Abraham Lincoln's wartime counsel to his Cabinet and argued Trump should focus on the ongoing Iran conflict before opening a second front [POLITICO]. The chairs of the Senate and House Intelligence, Foreign Relations, and Armed Services committees did not respond to POLITICO's questions on the subject.

Polling data confirms the ambivalence. Axios reported that Cuba has more than 300 military drones with discussed plans to use them to strike U.S. military installations, but a YouGov survey released in early May by the Center for Economic and Policy Research found that only 35 percent of Republican respondents supported going to war with Cuba, the same share that said they would oppose it, with 30 percent undecided [POLITICO]. On the Democratic side, the opposition is sharper but procedurally constrained. Sen. Mark Warner of Virginia, vice chair of the Senate Intelligence Committee, told POLITICO he would exercise "rigorous oversight of intelligence activities related to Cuba." Warner said there is "no existing authorization that would permit this administration to launch military action against Cuba," and that the administration had offered no legal or strategic argument sufficient to justify such action [POLITICO]. His framing is constitutionally precise: no Authorization for Use of Military Force covering Cuba exists, and the War Powers Resolution (50 U.S.C. § 1541 et seq.) would require the president to notify Congress within 48 hours of committing forces and to terminate any unauthorized engagement within 60 days absent congressional approval.

The administration's Cuba policy sits within a broader Western Hemisphere strategy. During his second term, Trump has implemented a "maximum pressure" campaign against Cuba as part of a broader strategy to assert U.S. primacy in the Western Hemisphere and limit the influence of adversaries such as China and Russia. Within days of his inauguration, Trump issued an executive order declaring that Cuba constitutes "an unusual and extraordinary threat" to U.S. national security, and authorized tariffs on goods from third countries that sell or provide oil to the island. That escalation followed the U.S. military operation in Venezuela in January 2026, which cut off Havana's primary oil supply ^[17]. Absent a congressional authorization or a dramatic Havana concession, the administration's choice is between sustaining an intensifying economic siege and forcing a legal and political reckoning over the use of force that, at present, it has not yet made the case for, even to its own Senate majority.
