Is Antarctica entirety claimed by USA and Russia?

Antarctica is not entirely claimed by the United States and Russia. Although these two countries have made significant claims to parts of Antarctica, there are several other countries that have also made claims. In total, there are seven countries that have made territorial claims in Antarctica. These countries are:

* Argentina

* Australia

* Chile

* France

* New Zealand

* Norway

* United Kingdom

The United States and Russia are the only two countries that have not signed the Antarctic Treaty, which was signed in 1959 and prohibits any new territorial claims in Antarctica. The United States and Russia have reserved the right to make claims in the future, but they have not done so to date.

The territorial claims in Antarctica are overlapping and have not been universally recognized. The Antarctic Treaty has frozen all territorial claims and requires that any disputes be resolved peacefully. As a result, Antarctica is governed by a unique system of international cooperation, which is designed to protect the continent's environment and scientific research.
