US does not need to ratify UNCLOS to lock in freedom of navigation rights

Assertion #1: The U.S. needs to join UNCLOS to “lock in” the navigation rights it currently enjoys under customary international practice. Implied in this argument is the presumption that other nations, the vast majority of which are UNCLOS participants, will ignore their obligations under the treaty and forgo the concurrent privileges regarding navigation rights afforded by customary international practice just because the U.S. is not a party to the treaty. This, according to the Bush Administration, will manifest itself in the form of some coastal states demanding notification by U.S. ships entering their waters or airspace.

Fact: These states have reciprocal interests in navigation rights that will discourage them from making such demands. Second, the few irresponsible states that may decide to make such challenges are not going to be dissuaded by the “locking in” argument or U.S. appeals to the navigation provisions of UNCLOS.
