With a $1 trillion modernisation programme signed off and atomic scientists deeply worried about the future, American policy on nuclear weapons is pretty much business as usual.
Is Australia's reliance on nuclear defence agreements keeping us on the wrong side of history?
Some are calling on the president to issue an apology when he visits Hiroshima. But an East Asia expert says his visit will focus on remembrance, and explains why that is enough.
