The Island, the Fuel Ship, and the Filter: Why Cuba's Energy Blockade Exposes Washington's Latin America Doctrine

Author's Note: This analysis reflects the perspective of Moemedi Michael Poncana. The Latin American story this week is not one of isolated leaders making isolated speeches. It is the continuing record of a region working out, in real time, how to be economically sovereign under an enforcement architecture designed to make that sovereignty impossible.
