Hosted by CSIS expert Rachel Ellehuus, “NATO’s Road to Madrid” explores how the United States’ most important alliance is approaching a critical process it has not undertaken since 2010: updating its Strategic Concept.

The last time NATO endorsed a formal strategy, Russia had not invaded Ukraine, China was not yet thought to be a challenge meriting NATO attention, and defense planners were only beginning to look at the military implications of climate change, hybrid warfare, and other challenges.

This podcast series will examine all these subjects, as well as how challenges from inside the alliance complicate its ability to respond effectively. Along the way, the series will try to help make sense of the inner workings of NATO, which are often opaque from the outside. In each episode of “NATO’s Road to Madrid”, Rachel will speak to guests with expertise on each item on NATO’s agenda as it adapts to this new era.
