23 июня 1961 года вступил в силу  договор об Антарктиде

Signed back in 1959, the treaty declared the mainland to be completely neutral and demilitarized, provided mutual assistance of different countries and freedom of scientific research. The treaty encourages international cooperation and prohibits nuclear explosions and disposal of radioactive materials. Today, the treaty already unites forty-six states. Scientific expansion, as opposed to a military one, is welcome.

By the way, there are only a few of neutral and entirely demilitarized zones on Earth. Perhaps the fact that neutral and fully demilitarized zones include the Moon and other celestial bodies may seem comforting in this situation.
