Why did the king not fight the German soldiers in Number the Stars?

In "Number the Stars" by Lois Lowry, the king of Denmark did not fight the German soldiers because he believed that a direct confrontation would lead to unnecessary bloodshed and suffering for his people. Instead, he chose to protect his citizens by maintaining a stance of non-resistance and encouraging acts of subtle defiance against the occupiers. His approach aimed to preserve the lives and dignity of the Danish people during the occupation.
