Last month, Barack Obama became the first US president in nearly ninety years to set foot in Cuba and the first ever to make an official state visit to the island. Obama’s trip came on the heels of his historic decision to re-establish diplomatic relations with Cuba — a move he hopes will burnish his foreign policy legacy and, equally importantly, solidify a sea change that even a hostile successor would find difficult to undo.

With Obama back stateside, discussion has now turned to the embargo — namely, what will happen if (or, more likely, when) it is lifted. Cruise ship companies are skirting the embargo’s remaining restrictions, launching “culturally themed” trips to Havana this spring. The number of US visitors to Cuba has increased 50 percent since Obama announced the rapprochement. And if the embargo disappears, the Guardian reports, Cuba “could see as many as 10 million US tourists a year — a deluge for which the creaking, crumbling bones of Havana are far from prepared.”

But it is not just the “creaking, crumbling bones of Havana” that are unprepared for the arrival of US consumers. The Cuban left may be even more vulnerable than the country’s infrastructure — and harder to repair.
