The UN law of the sea is a good treaty and should be upheld. The fact that some are saying it shouldn't be is simply ridiculous. These treaties exist for a reason, and if they were more regularly enforced, the net positive effects would be quite evident. It's time we enforce them more.
The US ratification of the Law of the Sea is a good decision. The US is known for not listening to the wishes of other countries, and by acepting the Law of the Sea it will improve its international standing by respecting the laws of the UN that many other countries have accepted.
