Belgian Gentlemen, actually Antarctica
From CoolAntarctica:
At this point there will be some much more contentious issues to be addressed:
Should it be allowed to drill for oil in Antarctic waters, or exploit other mineral wealth?
If it is, what environmental safeguards should there be?
Who do the oil / minerals belong to? (especially tricky one that)
Is the Antarctic Treaty sufficient to continue to govern and make decisions in these circumstances?
Will the countries who want the resources respect the Antarctic Treaty, or try to undermine it to get what they want for themselves?
The treaty is of course ignorable.
Also, don't forget territorial boundaries relating to colonization in the Americas, such as the Louisiana Territory
Here's something to consider for the Carribean:
