The US jurisdiction goes out 200 miles with the exclusive economic zone.
I do not remember the US Congress passing the UN Convention on the Law of the Sea (UNCLOS) which contains this 200 mile limit (exclusive economic zone - EEZ). When did that happen? I thought the bill was still in Congress however not acted upon as yet.
In the Gulf of Mexico I would think many countries would be tripping over each others 200 mile limit. I just don’t see mutual friends in nations battle for exploration rights of the sea bead (for oil/ng) in this EEZ. If it is the in the EEZ why would we allow a British company to drill rather than a US company? Doesn’t make real economic sense, except for an Administration that opposes drilling (for American companies on American territory).
