Harder Than It Looks 1986 one on netflix

A penetrating look at how difficult it is for the northern countries–Canada, Iceland, Norway, Sweden, Finland and Denmark–to remain neutral, caught as they are between the two superpowers. All but Canada were neutral before World War II. Today, only Sweden has not joined a military alliance, but with American and Soviet military forces in the northern seas, even its lone neutrality is at risk. Archival footage from the two world wars, animated maps, and interviews illuminate the historical shaping of each country’s stance on neutrality and approach to its own defense, and how these positions work for and against the countries. The film’s thesis is that a non-aligned north is the key to separating the superpowers and attaining world peace.
