US Tariffs Threat on Cuba’s Oil Imports Forces Mexican Diplomatic Tightrope

Washington has long used energy choke-points as leverage—from the 1941 oil embargo on Japan to the 1981 sanctions on Soviet gas pipelines—and the Cuba embargo dating back to 1962 shows how such pressure can endure for generations even when leadership changes. Trump’s 2026 decree extends the logic of extraterritorial sanctions, testing Mexico’s post-NAFTA dependency on US trade and its historic policy of non-intervention (the 1930 Estrada Doctrine). Sheinbaum’s balancing act illustrates how mid-sized exporters can be pinned between great-power politics and humanitarian concerns, a pattern likely to recur as fossil-fuel flows remain strategic even in a decarbonizing world. Whether this moment becomes a footnote or a pivot hinges on if energy weaponization accelerates regime change or merely deepens Cuba’s “Special Period”-style hardship; on a 100-year horizon, it may be remembered less for Cuba’s fate than for how sanctions culture reshaped the norms of international commerce.
