Is Cuba next? What the fallout from the Iran war means for Havana

“Cuba’s next,” said Sen. Lindsey Graham, a Republican and ally of U.S. President Donald Trump, after the U.S. and Israel began strikes on Iran.

The U.S. has imposed an oil blockade on the communist-run island nation since January, shortly after its ally and a key provider of oil, Venezuelan President Nicolás Maduro, was seized in an extraordinary U.S military operation. It has caused a worsening economic crisis and left Cuba facing its biggest test since the collapse of the Soviet Union.

Now Iran, with which Cuba has a strategic partnership, is under sustained attack. “This communist dictatorship in Cuba, their days are numbered,” Graham told Fox News’s “Sunday Night in America.”

Before the Iran strikes, Trump said he wanted a “friendly takeover” of the island, without giving details. The comments, alongside the U.S. attacks on Iran and Venezuela, have done little to allay growing fears in Havana, experts told CNBC.

A “friendly takeover” could resemble Venezuela in the aftermath of Maduro’s removal, “where you still have an authoritarian regime in power but moving in the direction and at the speed that the US determines,” said Carlos Solar, senior research fellow, Latin American Security at RUSI, a London-based defense think tank.

Solar told CNBC by email that Cuba had lost support from Venezuela and Iran “at a moment of maximum pressure” from the Trump administration.

But he added: “What is unclear is how the US will make the Cuban regime break, forcing Havana to capitulate.”

“We are not seeing the kind of military buildup prelude to operation Absolute Resolve that eventually led to Maduro being captured in January. It could well be that the US approaches Cuba in a totally different way,” Solar said.

A spokesperson for the White House and Cuba’s embassy in London did not respond to a CNBC request for comment.

Cuba’s Foreign Affairs Ministry has called for an end to the Middle East conflict and said it “condemns in the strongest terms” the joint U.S. and Israel attack on Iran on Feb. 28.

Russia recently warned that the situation in Cuba appeared to be escalating after Cuban forces killed four people who were off its coast in a U.S.-registered speedboat.

The blockade has effectively cut Cuba off from Venezuelan oil since launching a military operation to capture Maduro on Jan. 3. Cuba said 32 of its citizens were killed in the attack.

Trump has also said Cuba’s government poses “an unusual and extraordinary threat” and pledged to impose tariffs on any country that supplies it with oil. The U.S. Treasury said late last month, however, that it would allow the resale of Venezuelan oil to Cuba’s private sector.

The move appeared to reflect a small step to alleviate the island’s acute fuel shortage, which has forced a wave of airlines cut flights to the country. Tourism has long been a significant source of revenue for Cuba’s cash-strapped government.

Par Kumaraswami, professor of Latin American Studies at the U.K.’s University of Nottingham, told CNBC the Trump administration’s strikes against Iran and recent comments about Cuba’s regime had increased the mood of uncertainty and anxiety in Havana.

“Cubans are increasingly concerned about how they will survive in the midst of such global chaos, and the recent violence against Iran will have done nothing to allay their fears,” Kumaraswami said by email.

“At the same time, there are indications that the US administration is negotiating with the Cuban government regarding changes to Cuba’s economy, and this is indeed mirrored by Cuban President Miguel Díaz-Canel’s current focus on economic improvement as the priority,” she added.

Kumaraswami said the “message from Cuba” had been “constant” since the communists came to power in 1959: “Survival will only be achieved through adaptation to the changing geopolitical context.”

Cuba has adopted measures to protect essential services and ration fuel supplies for key sectors. The United Nations has previously warned of a possible humanitarian “collapse” as the country’s oil supplies dwindle.

“Cuba just bought itself a window — but it’s a narrow one,” Robert Munks, head of Americas research at risk intelligence company Verisk Maplecroft, told CNBC by email.

“The operation against Iran removes Cuba – temporarily – from Washington’s sights, as the US administration will be preoccupied with the Gulf campaign in the coming weeks.”

But Munks said he expected Cuba to return to the headlines, adding that the Cuban diaspora in South Florida would apply pressure and Washington has shown it is prioritizing the Western Hemisphere in its remodeled national security strategy.

“The regime in Havana remains in control, for the moment. Any unrest caused by economic hardship could be sudden and spontaneous, which would give Washington a pretext to refocus on pressuring the regime,” Munks said.
