According to the article, why did the U. S. not do more to respond to Nazi aggression and oppression of Jews?

In the decades since the Holocaust, some national governments, international bodies and world leaders have been criticized for their failure to take appropriate action to save the millions of European Jews, Roma, and other victims of the Holocaust. Critics say that such intervention, particularly by the Allied governments, might have saved substantial numbers of people and could have been accomplished without the diversion of significant resources from the war effort.In the decades since the Holocaust, some national governments, international bodies and world leaders have been criticized for their failure to take appropriate action to save the millions of European Jews, Roma, and other victims of the Holocaust. Critics say that such intervention, particularly by the Allied governments, might have saved substantial numbers of people and could have been accomplished without the diversion of significant resources from the war effort.Other researchers have challenged such criticism. Some have argued that the idea that the Allies took no action is a myth—that the Allies accepted as many German Jewish immigrants as the Nazis would allow—and that theoretical military action by the Allies, such as bombing the Auschwitz concentration camp, would have saved the lives of very few people. Others have said that the limited intelligence available to the Allies—who, as late as October 1944, did not know the locations of many of the Nazi death camps or the purposes of the various buildings within those camps they had identified—made precision bombing impossible.
