@Antarctica:Military
Military-note: the Antarctic Treaty prohibits any measures of a military nature, such as the establishment of military bases and fortifications, the carrying out of military maneuvers, or the testing of any type of weapon; it permits the use of military personnel or equipment for scientific research or for any other peaceful purposes
@Antarctica:Transnational Issues
Disputes-international: Antarctic Treaty defers claims (see Antarctic Treaty Summary above); sections (some overlapping) claimed by Argentina, Australia, Chile, France (Adelie Land), New Zealand (Ross Dependency), Norway (Queen Maud Land), and UK; the US and most other nations do not recognize the territorial claims of other nations and have made no claims themselves (the US reserves the right to do so); no formal claims have been made in the sector between 90 degrees west and 150 degrees west
