Revision of Customary international law is no longer sufficient to protect U.S. interests from Sat, 06/28/2014 - 14:18
Opponents of UNCLOS claim that the United States should not become a party because the United States already enjoys the benefits of UNCLOS through customary law and, therefore, should not unnecessarily incur the treaty's burdens. However, this ignores the fact that customary law can change and can also be influenced by how parties to UNCLOS decide to interpret its provisions.

Admiral Clark's statement indicates that becoming a party to UNCLOS will help solidify United States rights that now exist only in customary international law.95 Opponents of UNCLOS claim that the United States should not become a party because the United States already enjoys the benefits of UNCLOS through customary law and, therefore, should not unnecessarily incur the treaty's burdens.96 however, ignores the fact that customary law can change and can also be influenced by how parties to UNCLOS decide to interpret its provisions.97 If the United States is not a party, it will have no say as to how the law develops.98 By becoming a party to UNCLOS, the United States will be able to ensure that the law of sea develops in congruence with its national security and other interests.99
First, customary international law is, by its very definition, a fluid and changing concept. Vague on details, it is a constantly evolving process created by claim and counterclaim. As a result, there is much less agreement on the details of the customary Law of the Sea. Therefore, customary international law does not provide the kind of stability and predictability that we need for an uncertain political landscape. By contrast, the Convention locks in the rules that promote maximum maritime flexibility while at the same time ensures that coastal state interests are accommodated. This balance between maritime and coastal interests enhances the Conven- tion’s long term viability as well as its widespread acceptability among diverse inter- est groups. In short, the Convention will foster the legal stability that the United States and the rest of the international community has sought for so long.
The end of the Cold War has not changed the fact that many of our economic, political, and military interests are located far away from American shores. Recent events in Haiti, the Persian Gulf, the former Yugoslavia, Somalia, and Rwanda serve as important reminders that we still live in an uncertain and potentially dan- gerous world. While the specific threats and challenges that the United States will face in the years ahead undoubtedly will differ from those that dominated our think- ing over the past forty years, capable, vigilant forces will continue to be required to deter aggression and, if deterrence fails, to take necessary action.
The Convention provides the stability and predictability we seek to ensure the flexibility and mobility for our military naval and air forces, as well as our seaborne and airborne commercial activities around the world. By serving as a source of au- thority, the Convention guides the behavior of nations, promotes stability of expecta- tions, and provides a framework for issue resolution. In effect, it provides the legal predicate for our armed forces to respond to crises expeditiously and, importantly, at minimal diplomatic and political costs. And while the Convention may not pre- clude all attempts by coastal and archipelagic states to impede navigational freedoms, it puts the world community on notice that these freedoms have a solid legal basis and enjoy broad support among the major maritime and industrialized nations.
UNCLOS opponents are correct on at least one point. The customary international law of the sea – at least as generally understood today – is consistent with U.S. national security interests. The U.S. government has said as much.15"Statement of William H. Taft IV (April 8, 2004): Accession to the 1982 Law of the Sea Convention and Ratification of the 1994 Agreement Amending Part XI of the Law of the Sea Convention ." Testimony before the U.S. Senate Committee on Armed Services, April 8, 2004. [ More (10 quotes) ] However, in relying on the apparent harmony between UNCLOS and customary law as rationale for the U.S. to remain outside the treaty, opponents have failed to address a critical question: What if UNCLOS or customary law changes? Is it possible that today’s favorable legal environment could evolve adversely to U.S. interests?
The question is more than speculative. Through the years, a variety of nations have advanced legal theories inconsistent with critical U.S. ocean policy interests.16 Historically, these nations have lacked the will or ability to affect meaningful change in the international law of the sea. Today, however, this dynamic is changing.
Consider, for example, U.S. military operations in the off-shore area known as the EEZ, as codified by UNCLOS, comprising the waters beyond a nation’s territorial sea extending a maximum of 200 nautical miles from the coast.17 For years, the U.S. has consistently maintained the right under customary international law to conduct military activities in coastal state EEZs.18"Statement of William H. Taft IV (April 8, 2004): Accession to the 1982 Law of the Sea Convention and Ratification of the 1994 Agreement Amending Part XI of the Law of the Sea Convention ." Testimony before the U.S. Senate Committee on Armed Services, April 8, 2004. [ More (10 quotes) ] Over the past decade, however, the People’s Republic of China has initiated confrontations with U.S. ships and aircraft operating in the Chinese-claimed EEZ and its associated airspace. The Chinese have boldly rejected long-standing U.S. positions on customary international law and also challenged conventional interpretations of critical UNCLOS provisions.
Some states, especially developing nations, do not embrace customary inter- national law to the same extent that the United States and other maritime powers do. Those states view it as a body of law frequently formed without their participation and consent, law that only promotes the interests of developed nations—often former colonial powers. Developing countries prefer the relative certainty of inter- national agreements concluded on the basis of equality of nations.
Similarly, some Convention signatories, a number of whom are near or adjacent to important waterways used for international transit, have asserted that the Con- vention is a legal contract—and therefore its rights and benefits, such as transit passage and archipelagic sea lanes passage, are not available to non-parties. We do not accept these claimed restrictions on international transit rights, but such issues would be mooted under a universal Convention to which the United States is a Party.
As a recent example of potential difficulties, in July 1994, in the context of their right to exploit seabed resources in the strategic straits of Malacca, Malaysia stated that the ‘‘newness’’ of the transit passage regime casts doubts as to its status as a customary international law principle.
