We are away for Christmas, so this is a repeat of a previous episode.

Donald Trump has spent this year trying to negotiate a deal to end the war in Ukraine. So far, Vladimir Putin doesn’t seem interested in the US’ proposals.

One man who has experience successfully negotiating with Russia – and many other American adversaries – is Roger Carstens, former Special Presidential Envoy for Hostage Affairs. From 2020 to 2025 he worked to free dozens of US citizens taken hostage and wrongfully detained around the world, including Russia. Securing their release often required complex deals that took years to put together.
