Havana (CNN)Less than a month after seizing power in 1959, Fidel Castro embarked on his first trip as leader to seek support for his revolution. The young rebel leader's destination wasn't Moscow or Washington, it was Caracas.
The history that chains Cuba to Venezuela's crisis
Venezuela's government had secretly supported Castro and his rebels with funds and weapons during their fight to oust US-backed dictator Fulgencio Batista. Now a victorious Castro had a new request: Loan Cuba $300 million dollars worth of oil.
The oil shipments would be "a master trick on the gringos," Castro told then-Venezuelan president Rómulo Betancourt, breaking Cuba's economic dependence on the US. Not wanting to upset Washington, Betancourt frostily replied that if Castro wanted Venezuelan oil, he should buy it on the open market.
But Castro got what he wanted, in the end. Today, Venezuelan oil is the lifeblood of Cuban economy, under a barter system where Cuba receives billions of dollars of crude in exchange for Cuban doctors, teachers, sports trainers, and military and intelligence advisers. And now, as political unrest threatens the Maduro régime in Caracas, it also threatens to put the lights out in Havana.
Maduro's rival, Juan Guaidó, has vowed to end Cuban influence in Venezuela, and any change in government could upset the special relationship between the two countries. Shipments from Venezuela have become less frequent, and Cuba is hurrying to expand how much oil it can store. "Our calculation is Cuba has 5 million barrels of total primary storage," says Jorge Piñón, a Cuba energy expert at the University of Texas in Austin. "I am saying if Cuba has a crisis, Cuba has enough oil to last them 35 to 45 days."
So far Cubans have not experienced a shortage. But many still remember the painful end of another special relationship, which led to widespread blackouts and drove Cuban refugees toward the United States: the so-called "Special Period" in the 1990s, when the USSR collapsed.
When Castro first approached Venezuela in 1959, he envisioned a leftist government in control of its massive oil riches, which could support like minded regimes across the region and finally challenge Washington's control of the hemisphere.
Instead of Venezuela, it was the Soviet Union that ultimately provided crucial support to the Cuban revolution, becoming the island's main trading partner and sending thousands of military and intelligence advisers to island. But Castro never forgot Venezuela's potential, and backed several failed attempts at revolution beginning in the 1960s.
After the dissolution of the Soviet Union in 1991, Cuba found itself in dire need of new friends. The economy on the communist-run island had all but collapsed without Soviet support. Called "the Special Period" in Cuba, Cubans endured wartime food rations, daily blackouts of electricity while thousands of citizens fled the island on rafts.
In 1998, the stars seemed to align for the Cuba-Venezuela alliance that Castro had dreamed of: Hugo Chavez, a charismatic former Army paratrooper, was elected to the Venezuela's presidency. Like Castro, Chavez had led a thwarted uprising but used that failure to raise his profile.
After time in jail, Chavez came back to win an upset victory. Both men could speak for hours, casting a spell over their supporters, and both swore to erase the gap between rich and poor in their countries.
Castro would eventually take the role of the elder statesmen, and Chavez his heir to the mantle of the leader of the Latin American left.
In the early 2000s, Castro and Chavez struck a barter deal that pulled Cuba from the depths of its economic crisis with generous dose of petroleum. "Cuba got access to the largest oil reserves on the planet, in exchange for sending doctors and coaches and intelligence advisers and military advisers," Geoff Ramsey of the Washington Office on Latin America tells CNN.
Soon Venezuela was sending the island roughly 100,000 barrels of oil a day to the island. In exchange, Cuban doctors set up clinics for the poor — Chavez's political base — in Venezuela's most downtrodden neighborhoods, and thousands of Venezuelans traveled free of charge to Havana for medical treatment of everything f
