Cuba in the Crosshairs

In early 2026, U.S. leaders sharply escalated pressure on Cuba’s communist government. President Trump has floated a “friendly takeover” of Cuba and vowed to “take Cuba in some form,” claiming he can do “anything I want” with the island ^[1]. Secretary of State Marco Rubio has similarly urged that Cuba “has to get new people in charge” ^[2]. These statements accompany an aggressive sanctions campaign: Washington cut off all Venezuelan oil shipments (Jan. 11) and on Jan. 29 issued an order declaring Cuba an “extraordinary threat” and imposing tariffs on any country selling oil to Cuba ^[3]. The result is a fuel blockade that has caused nationwide blackouts and shortages in Cuba ^[4]. With Venezuela dealt with and pressure on Cuba, and the rest of the world wonders, “What happens next”?

Cuba in a boiling pot:

Since the 1960s, U.S.–Cuba relations have centered on the embargo and Cold War tensions, see-sawing back and forth between de-escalation and rampant escalation. In 2026, the situation has taken a dramatic turn. In a surprise Jan. 3 operation, U.S. special forces captured Venezuela’s President Nicolás Maduro ^[5], who was a close ally of Cuba’s government. This victory emboldened the Trump administration to target Havana. Within days, Trump declared that “Cuba is ready to fall” and cut off Venezuelan oil exports to Cuba ^[6]. On Jan. 29, he issued an executive order under a declared national emergency, threatening tariffs on any country that supplies Cuba with fuel. Cuba now faces crippling blackouts. The electricity grid even collapsed for the entire 11 million population in mid-March ^[7]. Meanwhile, U.S. officials hint at regime change. Trump has publicly mused about taking Cuba (even calling it an “honor”) and said Cuba is a “failing nation” that “will be failing pretty soon”. Rubio, a Cuban-American hardliner, has asserted Cuba’s communist system “doesn’t work” and called for “new people in charge”. They also deny responsibility for the crisis, blaming only Cuba’s government for economic failures ^[8].

These developments have prompted frantic international diplomacy. Cuba has kept channels open, with officials claiming readiness to talk ^[9], but insisting that regime change is non-negotiable ^[10]. U.S. media report secret talks are underway, even as U.S. negotiators reportedly told Havana, “Diaz-Canel must go.” But with both sides posturing and the island in crisis, analysts warn the situation could spiral.

The past months have seen a flurry of milestones.

President Trump publicly announced on Feb. 27 that the U.S. could “very well end up having a friendly takeover of Cuba”. On March 16, Trump told reporters at the White House that he expected to “have the honor of taking Cuba” and boasted, “I can do anything I want” with the country. Rubio has echoed the hardline stance: on March 17, he told a Washington audience that Cuba’s current leaders “don’t know how to fix it” and “have to get new people in charge”. Both men have signaled that the U.S. goal is to replace Cuba’s leadership, not merely to alleviate suffering.

Meanwhile, U.S. policy actions have tightened the economic vise. Immediately after the Venezuela raid, Trump announced on Jan. 11 that “no more Venezuelan oil or money would flow to Cuba”^[11]. Weeks later, he formalized that policy with a national emergency order threatening punitive tariffs on any foreign country supplying Cuba, with reports suggesting the Pentagon considered a naval blockade of all oil shipments to Cuba. The administration says these measures target the Cuban regime’s “malign actions” abroad, but Cuba has responded sharply. Foreign Minister Bruno Rodríguez denounced the sanctions as “fascist, criminal, and genocidal” and accused the U.S. of “blackmail” to enforce an illegitimate blockade. UN human rights experts have gone further, calling the fuel embargo a “serious violation of international law” and “collective punishment” of Cuba’s civilians ^[12] .

Cuba instantly felt the impact. No Venezuelan oil has arrived since early January, and Mexican imports have halted under U.S. pressure. By mid-March, Cuba’s grid failed entirely, stranding its 10 million people in darkness. These crises have, ironically, opened back-channel talks, with the U.S. quietly engaging Cuban negotiators in February to forestall disaster. But both sides maintained hard lines. Cuba vowed to resist U.S. intimidation, while Trump said, “Cuba’s next, by the way, but pretend I didn’t say that.” The current moment is one of unprecedented U.S. hostility toward Cuba and open talk of regime change, resembling an atmosphere likened by analysts to early Cold War brinksmanship.

How to go about it

If diplomacy fails, what military options could the U.S. consider? Pentagon commanders insist no invasion is planned, but similar things were said about Venezuela. Some key options include:

1. Blockade or seizure of shipping: The U.S. Navy could attempt to interdict tankers and fuel shipments to Cuba, a classic blockade, having already been suggested by “some close to Rubio”^[13]. This would amplify blackouts and shortages, and invite Cuban diplomatic protests and pleas to allies. Cuba would likely appeal to the UN or OAS for solidarity, and might attempt to smuggle or negotiate alternate supplies (as Russia did). Cuba could attempt to respond violently, but the odds of this are generally low, not wanting to bait Trump into an open conflict that Cuba cannot hope to win.
2. Air strikes or no-fly zone. The U.S. could declare a no-fly zone over Cuba or carry out precision air strikes. In that case, Cuba would almost certainly activate its S-125 missile batteries and scattered SAM sites, responding to U.S. aircraft. Even though its aircraft are largely vintage trainers (only ~20 operational planes, no modern fighters ^[14]), its air defenses can still threaten low-flying planes. Cuba would hail such moves as an act of war, likely mobilize ground forces and coastal batteries, and possibly sink blockading ships. This option is not likely to be taken, as Trump will likely want to avoid an all out protracted conflict, and will look to overwhelm them in a single day, ala Venezuela.
3. Cyber and electronic warfare. The U.S. could use cyberattacks to disrupt Cuban infrastructure (power grid, communications, air traffic control). This option can remain below the threshold of outright kinetic war, but still exacerbate Cuba’s crisis. Cuba’s response would be to harden systems where possible and accuse the U.S. of covert aggression. This will likely be employed, similar to Venezuela, as a precursor to a special operations raid.
4. Special operations raids. Inspired by the Venezuela raid, the U.S. could send commando teams to capture or eliminate Cuban leaders. Cuba would treat this as an invasion attempt, likely responding with full military resistance and rallying the populace.
5. Sanctions and economic warfare. Beyond oil, the U.S. can tighten broader sanctions. Indeed, Treasury is likely poised to cut Cuba off from any remaining foreign credit. These tools could further strain Cuba’s economy. Cuba would respond with nationalist rhetoric and a crackdown on dissent (as happened after the 2021 protests), while seeking aid from allies.

On Cuba’s side, the overall military balance is stark. Cuba has at most a few dozen combat aircraft (primarily Soviet-era trainers and transports) and modest air defense (some S-125/S-75 SAM sites and older anti-aircraft guns). Its navy is tiny (around 30 small vessels, no blue-water ships). On land, Cuba fields only a few hundred aging tanks (mostly T-54/T-55 types) and artillery pieces.

If the U.S. employed even a limited air/naval force, Cuban defenses would collapse quickly, even if a short war could produce thousands of casualties. U.S. Southern Command officials have acknowledged being ready to defend American facilities but insist “we are not rehearsing any invasion” of Cuba.

How do I look?

A U.S. attack on Cuba would face serious legal and diplomatic hurdles. The U.S. would be violating the UN Charter’s ban on unilateral aggression ^[15]. Even the current oil blockade was decried by UN human rights experts as a breach of international law. According to the U.N. experts, declaring Cuba an “extraordinary threat” and coercing third countries not to trade with it violates core principles of sovereignty and non-intervention. They warned that U.S. tariffs and embargoes amounted to “collective punishment” of Cuban civilians. Any military strike would similarly be deemed illegal aggression without self-defense justification, and the U.S. can hardly claim Cuba posed an imminent threat to justify force under Article 51.

Domestically, U.S. law would nominally require at least notification to Congress. Given the scant public support for a war over Cuba, Congress might balk at authorizing an unprovoked invasion. This assumes that Congress is even notified of an operation and gives authorization beforehand. There is currently no authorization from Congress for a war in Iran.

Regionally, the fallout would be explosive. Many Latin American governments (especially left-leaning ones) will condemn U.S. moves. Mexico’s president, Claudia Sheinbaum, has paused oil shipments but has provided humanitarian aid to Cuba. Chile’s outgoing president, Boric, pledged financial support, and Venezuela’s government (Delcy Rodríguez’s interim regime) openly rejects U.S. pressure and reaffirms solidarity with Cuba. By contrast, U.S. allies such as Colombia, Uruguay, and Ecuador have largely remained silent or tacitly approved of the actions^[16]. The Organization of American States (OAS) is deeply split: U.S.-aligned states could block condemnations, but a majority of Latin members might support Cuba’s right to sovereignty. Outside the hemisphere, Cuba’s guarantors (Russia and China) have already voiced support. Moscow publicly dispatched oil to break the blockade and warned the U.S. to back off ^[17].

Humanitarian and economic consequences would be severe. Cuba’s own reports and UN agencies warn of dire outcomes: long blackouts have already disrupted hospitals, food storage, water, and sanitation. The weakened economy is now completely paralyzed with shortages of medicine and fuel. If some conflict did arise, refugees would flee to Florida or Latin America, creating a regional crisis.

In a best-case scenario, intense diplomacy could yield a compromise. One in which the U.S. eases some sanctions in exchange for reforms by Havana, with Cuban concessions on political freedoms or economic opening.

The most likely scenario today seems to be continued U.S. pressure short of invasion. Forcing fuel shortages to deepen and internal dissent to grow, potentially forcing some change in leadership or policy over time.

The worst-case scenario is open military conflict. A limited U.S. strike or blockade mishap escalates into a full invasion, leading to armed resistance, heavy casualties, a collapse of the Cuban government, and a dangerous vacuum on the island. Such a war would almost certainly draw in Russia and risk a broader confrontation.

Conclusion

While Trump and Rubio frame it as supporting Cuban freedom, coercing a nation at gunpoint could backfire. To reduce the risk of conflict, sane policymakers would want to prioritize multilateralism and pragmatic action.

First, drop all aggressive measures: the U.S. should drop talk of blockades or military action and not further sanction allied countries that assist Cuba.

Second, pursue earnest diplomacy: use reopened channels to negotiate relief for Cubans in exchange for credible reforms. Involve neutral mediators to ensure any outcome respects Cuba’s sovereignty.

Third, work with regional partners: consult with other American states through the OAS to seek a hemispheric consensus.

Finally, prepare humanitarian aid: if embargoes continue, the U.S. and allies should fund an international relief effort to prevent a humanitarian catastrophe.

But these recommendations will not be heeded. Wise, calculated action is for the boring losers who don’t want to flex their might as the strongest country in the world. For an outdated, traditionalist communist Cuba to survive, it will need to navigate the situation carefully. Those entrenched in power over nearly 60 years of communism will not want to modernize so easily. Whether they can placate Trump long enough for him to become distracted by something else is another matter entirely.
