U.S. national interest harmed by remaining outside UNCLOS regime and unable to take advantage of Arctic boom

The good news is that it’s not too late to play catch-up. The first and most obvious place for the United States to start is to finally join the 164 other countries that have acceded to unclos. Ironically, Washing- ton had a hand in drafting the original treaty, but Senate Republicans, making misguided arguments about the supposed threat the treaty poses to U.S. sovereignty, have managed to block its ratification for decades. The result has been real harm to the national interest.

UNCLOS allows countries to claim exclusive jurisdiction over the por- tions of their continental shelves that extend beyond the 200-nautical- mile exclusive economic zones prescribed by the treaty. In the United States’ case, this means that the country would gain special rights over an extra 350,000 square miles of ocean—an area roughly half the size of the entire Louisiana Purchase. Because the country is not a party to unclos, however, its claims to the extended continental shelf in the Beaufort and Chukchi seas (and elsewhere) cannot be recognized by other states, and the lack of a clear legal title has discouraged private firms from exploring for oil and gas or mining the deep seabed. The failure to ratify unclos has also relegated the United States to the back row when it comes to establishing new rules for the Arctic. Just as traffic through the Bering Strait is growing, Washington lacks the best tool to influence regulations governing sea-lanes and protecting fisheries and sensitive habitats. The treaty also enshrines the international legal principle of freedom of navi- gation, which the U.S. Navy relies on to project power globally.
