By removing guardrails around nuclear weapons, the Trump administration is making the world a far more dangerous place.

On this episode of After America, Jon B Wolfsthal, former Special Assistant to President Obama for National Security Affairs, joins Dr Emma Shortis to discuss the expiry of the New START nuclear weapons treaty between the United States and Russia, AUKUS and Australia’s nuclear capabilities, and why “nuclear weapons are back with avengeance”.

This discussion was recorded on Thursday 12 February 2026 Australian time.
