Why did Nazi Germany NOT invade Sweden?

Moreover, an agreement from the dissolution of the union between Norway and Sweden in 1905 stated that no fortification was allowed along this border. One of Germany's demands on Sweden, as Germany's invasion progressed, was that Sweden was not to mobilize.

Nazi Germany did not invade Sweden because Sweden was a neutral country  and didn't take either side of the war.

Hope this helps :)

the great wall of china worked as a defense for the feudal states of the zhou dynasty to the north. during the warring states period more walls were put up to defend the borders of the different kingdoms. it was semi successful because despite the wall, the mongols eventually conquered china also the great wall provided protection to the economic development and cultural progress, safeguarded the trading routes such as the silk road, and secured transmission of information and transportation. @jayxboof
