It’s not paranoia. In the fourth quarter of 2025, Venezuela sent Cuba about 35,000 barrels of oil a day. While that isn’t enough to keep all the island’s lights on, its industry functioning and its transportation flowing, it has kept the essential gears of our nation in motion. Losing that fuel, or having it drastically reduced, would be a severe shock to an economy that is exhausted, low on foreign currency, and increasingly constrained by American sanctions. Already a U.S. blockade of tankers has cut off some of the supply, and Mr. Trump on Sunday declared that Venezuela would send “no more oil or money” to Cuba.
