Australian naval expert Jennifer Parker joins Ray and Jim to talk about the nuclear-powered submarines Australia will be acquiring as a result of the new trilateral Australia-UK-US (AUKUS) partnership. Jen discusses the advantages of nuclear-powered submarines over their diesel-powered cousins, and the reactions of Australia's neighbors to the abrupt AUKUS announcement. She also explains the distinction between nuclear power and nuclear weapons, and how confusion over these terms played a role in the controversy surrounding the deal. Jen unpacks the risks involved with such a significant leap in technology--such as its high cost and the country's lack of nuclear expertise and infrastructure--and how Australia is working to mitigate those risks. Jen takes on some of the AUKUS deal's critics, including those who believe Australia should prioritize a close-in defense of Australia. Finally, in our "There I was ..." segment, Ray tells the story about how he had to learn English all over again when he served in Australia.
