Why do you think the Allies did
not respond to the forced removal, or ethnic cleansing,
and genocide of Jews in countries under Nazi control?

The Allies were concerned with the treatment of Jews in Nazi control.

Explanation:

While the war effort was not entirely because of the German policy on Jews it was a huge part of the effort and many countries had Jewish battalions that were fighting for the cause of their fellow sufferers.

The allies tried to free the Jews from the Nazis and in the end were also responsible for the formation of the new Jewish state in Israel and took up a huge population of refugees in too in their own countries.
