Falklands Oil: The $2.1B Sea Lion Field Behind Trump's Sovereignty Threat

# Falklands Oil: The $2.1B Sea Lion Field Behind Trump's Sovereignty Threat

> **Quick answer:** A leaked Pentagon memo prepared by Elbridge Colby, the Trump administration's top policy adviser, proposes reviewing US diplomatic support for UK sovereignty over the Falkland Islands — punishment for Britain's initial refusal to back the Iran war. The memo lands just four months after a $2.1 billion final investment decision was taken on the Sea Lion oil field, which sits atop an estimated 800 million barrels with first oil planned for 2028. This is not a diplomatic spat. It is a resource dispute dressed as one.

The Falkland Islands are back at the center of a geopolitical crisis — and the timing is not a coincidence. In December 2025, the Sea Lion oil field cleared its final investment hurdle after 15 years of delays. In April 2026, a leaked Pentagon memo surfaced proposing that the US review its support for British sovereignty over the islands. In between: Argentine President Javier Milei, one of Donald Trump's closest international allies, declared he is doing "everything humanly possible" to return the Falklands to Argentina.
