Last week, Donald Trump instructed the Pentagon to “immediately” resume US nuclear weapons testing.

The order breaks with more than three decades of protocol for the United States – justified, according to the president, by the actions of China and Russia.

And as these nuclear-armed powers expand and modernise their arsenals, countries closer to Australia are openly debating whether to follow.

Today, professor of strategic studies at the ANU and a contributor to Australian Foreign Affairs, Brendan Taylor, on what Trump’s announcement means for the nuclear arms race, and what happens if our neighbours go nuclear.
