Diplomats based in Havana are voicing growing concern over Washington’s escalating pressure campaign against Cuba, even as they quietly prepare contingency plans in case conditions worsen. In the leafy Siboney district, officials from countries traditionally aligned with the United States say frustration is mounting over what they describe as a lack of clarity from U.S. representatives about what would follow any potential collapse of Cuba’s government.

Cuba is already facing a severe crisis. Years of economic decline, hyperinflation, and the emigration of nearly one-fifth of its population have left the country deeply weakened. After U.S. action against Venezuela earlier this year, Washington has intensified efforts that critics say amount to pursuing regime change in Havana, primarily by restricting oil supplies.

Fuel shortages are now compounding humanitarian concerns. The lack of oil is disrupting electricity, water, transportation, and food distribution, while also hampering relief efforts by the UN World Food Programme. Airlines from Canada and Russia have suspended flights due to aviation fuel shortages, dealing a blow to tourism — a vital source of foreign currency.

Inside Cuba, universities and public offices have closed, transportation has been reduced, and citizens are bracing for further hardship. Diplomats fear urban centers could face acute suffering within weeks, prompting some embassies to consider scaling back operations if the crisis deepens.
