Answer:
The Nazis controlled Poland as well.
Step-by-step explanation:
In 1938, Germany expelled all Polish Jews from its borders, leaving them without a home or country. When they tried to return to Poland, they were unable to do so because the Nazis had taken control of the country and were implementing their anti-Semitic policies there. The Polish Jews were effectively trapped, as they could not return to their homes and were not welcome in Germany.
