The Trump administration recently completed its AUKUS review, including a directive from President Trump to proceed “full steam ahead” on AUKUS Pillar I.

Is AUKUS Pillar II fit for purpose? Which advanced capabilities can deliver the best return on investment in the near term? Is AUKUS Pillar II a “solution in need of a problem”?

Recently, a gunman killed four people and wounded eight at a Latter Day Saints (or Mormon) church in Michigan. President Trump described this as “yet another targeted attack on Christians in the United States of America” – but there are distinct differences between this and other high-profile shootings. How was this similar to or different from other attacks on religious institutions in America? What are the motivations behind these attacks? Is there a throughline between the assassination of Charlie Kirk and an attack on an LDS church in Michigan? Associate Professor in American Politics and Foreign Policy at the United States Studies Centre David Smith joined the podcast to discuss these questions. He is one of Australia’s leading experts on religious persecution in America and is the author of Religious Persecution and Political Order in the United States.
