Trump’s new executive order doesn’t just target Havana; it weaponizes Cuba’s last lifeline. By threatening tariffs on any country that sells oil to the island, Washington is signaling that helping Cuba—even for humanitarian reasons—could carry a direct economic price in the U.S. market. Mexico, now Cuba’s main supplier, is caught in the crossfire: a USMCA partner forced to choose between regional solidarity and avoiding a showdown with its largest trading partner.

For Cuba, the stakes are existential. Fuel shortages already mean blackouts, paralyzed hospitals, and deepening hunger. Supporters of the order insist only maximum pressure can break a regime entwined with Russia, China, Iran, and regional proxy networks. Critics warn it crosses a moral line, punishing civilians to make a geopolitical point. As agencies debate how far to go, one reality is clear: this isn’t just about Cuba’s oil. It’s a test of how far “America First” will reach into the hemisphere’s future.
