The International Geophysical Year puts twelve nations on the ice at once
Twelve countries establish and operate Antarctic stations simultaneously for the duration of the IGY, explicitly setting aside the question of whose territory they stand on. Vostok and several other long-lived stations date from it. The arrangement worked for eighteen months, and the treaty signed the following year is essentially an attempt to make that temporary suspension of the sovereignty question permanent.
Historical — it happened, and the record is settled.

The Antarctic Treaty
The Treaty reserves Antarctica for peaceful purposes and prohibits military activity (Article I), guarantees freedom of scientific investigation, freezes the territorial claims question so that no act while it is in force constitutes a basis for asserting, supporting or denying a claim and no new claim may be made (Article IV), applies to the area south of 60 degrees south (Article VI), and provides for inspection of all stations, installations and equipment by observers designated by consultative parties (Article VII). V55 VERIFICATION BASIS: this session had NO working research channel - WebFetch to ats.aq was refused by the network egress proxy and the WebSearch budget was exhausted before production began. The citation rests on the producer's prior knowledge of the treaty text, not on consultation during production, and must be opened before publication.
