Cuba's Universities Go Fully Remote as U.S. Oil Blockade Deepens

U.S. pressure on third-party tankers supplying Cuba has cut fuel deliveries for nearly three months, forcing universities to abandon in-person classes entirely since February. The shift from hybrid models reflects infrastructure collapse: blackouts now disable the internet and devices those models require. Cuba produces only 40% of its own oil, leaving it structurally exposed to supply disruptions.
