U.S. pressure on Cuba is collective punishment — cutting off oil has plunged ordinary Cubans into 15-hour blackouts, food shortages and economic collapse while doing nothing to dislodge the regime. History proves this approach fails every time, from Kennedy's embargo to Bush's travel restrictions. The Cuban Communist Party is far more durable than Maduro's fractured government ever was, making Trump's regime-change fantasy a dangerous, costly delusion.
