Talk In Circles - Hercules

Pretty obviously about nuclear threat but I want to say why - Hercules itself is the name of a class of nuclear sub, - "Here comes the submarines". "Why wait for the planes to come" could refer to Australia's allowance of American bombers to land on her territory. The phrase "South Pacific carry-on" could be reference to the treatment of NZ in the ANZUS pact.

Hercules are also a classe of military transport planes. During the French gigs, Garrett introduces it as a song about the Rainbow Warrior sabotage by the French secret service, in 1984 or 1985, I'm not sure.
