1940, when Hitler was about to kill Switzerland, why did he suddenly stop at the last minute? Any stories?

When Germany worked hard after World War I and vowed to avenge its defeat in World War I, the comfortable days of European countries ended. As a result, Austria, Czech Republic, Poland, France, Belgium, Netherlands, Luxembourg, Yugoslavia, Greece and other countries were successively occupied by Germany, and Britain was also severely hit. Even vast areas of the western Soviet Union were occupied by the Germans. So why did Switzerland escape when Germany kept occupying all parts of Europe? Are there any other stories in this?

German

First of all: strategic location is not important.

When Germany occupied Austria and France, Switzerland had become a turtle in a jar, surrounded by Germany from the north, west and east, and only Italy was in the south of Switzerland, so Switzerland was completely surrounded by the Axis countries. So it doesn't matter whether Germany occupied Switzerland or not. Germany finally spared this tiny country.

Secondly: Switzerland's high vigilance When Germany took the lead in attacking Poland, Switzerland maintained a high vigilance attitude towards this neighboring country, not only expanding its troops to prepare for war, but also mobilizing more than 500,000 troops. At the same time, Switzerland is a country where all the people are soldiers, ready to invade Germany.

Third, the influence of topography Switzerland is a mountainous country with many mountains, rugged terrain and dense rivers. If we want to conquer here, the German armored forces will be blocked by the terrain and lose the characteristics of quick surprise attack, which is not cost-effective for Germany.

Finally: neutral country Although the word neutral country is not important to Germany, as the headquarters of the Geneva International Red Cross, in order to create a good image, Germany finally chose not to invade this country, which is not worth the candle. So at the last moment when the Germans were about to invade Switzerland, they chose to give up.
