What was the Truman proclamation?

The Truman Proclamation, officially known as Proclamation 2667, was issued by President Harry S. Truman on September 28, 1945. It declared the United States' intention to assert sovereignty over the continental shelf and its resources, establishing a policy that the U.S. would control the exploration and exploitation of Natural Resources found in the seabed and subsoil of the continental shelf. This proclamation laid the groundwork for future U.S. ocean policy and influenced international discussions on maritime boundaries and resource rights.
