Opportunity cost to US of not joining UNCLOS is greater vulnerability to excessive lawfare claims hampering mobility and access rights

Since development of customary international legal norms is disproportionately shaped by the positions and actions of the world's most politically, economically, and militarily influential nations, the traction of an emerging "securitization" norm could potentially increase as leading state proponents, such as China and India, continue to gain political, economic, and military stature. Similarly, while the actions of landlocked nations can play a role in the development of customary international law of the sea, the role of coastal nations is particularly influential in this regard. However, while crystallization ofa "securitization" norm into customary international law would clearly constitute ultimate success for a nation state "lawfare" practitioner, more realistic intermediate goals are achievable. For example, a coastal nation may successfully dissuade an expeditionary nation from challenging an excessive claim by exploiting the expeditionary nation's political vulnerability or desire to avoid military escalation. Additionally, a coastal nation may effectively undermine an adversary's legitimacy through consistently pressed, specious claims. In either case, an expeditionary nation such as the United States risks incurring additional diplomatic and political costs if it chooses to persist in contested operations. These costs can be conceptualized as "drag" on the U.S. government's ability to protect sea lines of communication, collect intelligence, conduct military hydrologic survey operations, and maintain the required force structure to accomplish these. Therefore, the opportunity costs associated with non-membership in UNCLOS can be meaningfully correlated to the vulnerabilities associated with maritime "lawfare"-operational latitude, legitimacy, and maximal effective ability to influence maritime law and policy.
