This week, The House revisits an in-depth documentary from the summer, as NATO’s secretary general has warned Russia could launch an attack on the alliance within the next five years. Talk to NATO’s two newest members, Finland and Sweden, and they’ll tell you preparation involves a lot more than just boosting military spending.

As Canada seeks to strengthen ties with both countries, what can we learn from our newest NATO allies about preparing for the worst? Supported by the R. James Travers Foreign Corresponding Fellowship, CBC's Emma Godmere travelled to the two Nordic countries to visit bomb shelters, the Russian border and military training grounds north of the Arctic Circle to see and hear how Finns and Swedes are steeling themselves for whatever the future may bring.

This week on The House: Three Parliament Hill watchers square off against each other to see who can remember the most from a very eventful and consequential year in Canadian politics.

After eight years in Washington, Canada's U.S. ambassador Kirsten Hillman is coming home. Over that time, she has seen Canada's relationship with the United States transform, for better and for worse. As she prepares to step down from her ambassadorship, she explains in an extended interview with host Catherine Cullen how she’s built critical connections in the U.S. capital — and whether she believes there’s a limit to what Trump can do.

Plus, author and former presidential speechwriter David Frum believes the American empire is in decline. He reflects on what Canadian democracy can learn from this moment and why he believes a stronger sense of national pride is critical for Canada’s future.
