Ash Bhardwaj travels to Finland to find out how this northern European country came to abandon nearly 80 years of military non-alignment and become NATO’s newest member. He speaks to conscripted soldiers on Finland’s frontline, takes a tour around the home of one of the country’s most important artists and visits Helsinki’s Centre of Excellence for Countering Hybrid Threats to hear how Finland’s “total defence” mentality keeps it safe.
