In page Liechtenstein:

"

During World War II, Liechtenstein remained officially neutral, looking to neighbouring Switzerland for assistance and guidance, while family treasures from dynastic lands and possessions in Bohemia, Moravia, and Silesia were taken to Liechtenstein for safekeeping. Operation Tannenbaum, the Nazi plan for conquest of Switzerland, also included Liechtenstein, and the Nazi "Pan German" dream of uniting all German-speakers in the Reich would have also included the population of Liechtenstein. However in 1944, the Nazis abandoned implementing this plan after the Allied invasion of France, and Liechtenstein was spared from enduring a Nazi occupation.[citation needed]
