Mark Goldberg has some further background and information on the UN Convention on the Law of the Sea. Meanwhile, Cato's Chris Preble points to a debate between Doug Bandow (last seen in a cash-for-comment scandal) and Raj Purohit from Citizens for Global Solutions over at the Partnership for a Secure America.
Frank Gaffney's also against this treaty, so I think you could say this treaty has all the right enemies. Basically, internationalists and establishmenty business types seem to be for it, and really paranoid UN-haters are against it.
