What is the political status of Antarctica?

Under several treaties including the Antarctic Treaty of 1959, Antarctica is a politically neutral site. Unilateral and multilateral scientific outposts are allowed, but no military or industrial facilities can be constructed. Several countries have retained claims to various regions, but have agreed for the most part to waive these rights and allow Antarctica to remain a scientific preserve for the foreseeable future.

All of planet earth south of 60 degrees S, is governed by the Antarctic Treaty. The treaty, as above, is a-political. Territorial claims are held in abeyance and no future territorial claims can be made. This land is dedicated to the scientific pursuit answering questions about the health of planet earth.
