Regarding early reports of the Holocaust during World War II, the immediate response by President Roosevelt and the United States government was to focus on winning the war as quickly as possible (a), but to do nothing to ease the suffering and slaughter of the German civilians being herded to their deaths.
Refugees who had survived and escaped the concentration camps met in person with President Roosevelt and described what was going on there, and newspapers in the United States reported Nazi atrocities against European Jews, as early as 1942. The reaction of the general public to these reports was denial that such reports could be true (d), and little or nothing was done to interfere with that barbaric inhumanity, for another three years !
Based on the information in the excerpt, the United States brought Nazi leaders to military tribunals in Germany (a) AFTER the end of the war, but did little or nothing to address the dire suffering and slaughter of millions of civilians in Germany DURING the war.
