What is "finlandization"

Finlandization (; ; ) is the process by which one powerful country strongly influences the policies of a smaller neighboring country, while allowing it to keep its independence and its own political system. The term literally means "to become like Finland" referring to the influence of the Soviet Union on Finland's policies during the Cold War.

The term is generally considered pejorative, originating in West German political debate of the late 1960s and 1970s. As the term was used in Germany and other NATO countries, it referred to the decision of a country not to challenge a more powerful neighbour in foreign politics, while maintaining national sovereignty. It is commonly used in reference to Finland's policies in relation to the Soviet Union during the Cold War, but it can refer more generally to similar international relations, such as Denmark's attitude toward Germany between 1871 and 1940, or the policies of the Swiss government towards the German Nazi regime immediately before World War II.
