Refer to the passage. "Fifty years ago, somewhere in the Carpathian Mountains, a young Jewish woman read in a Hungarian newspaper a brief account about the Warsaw ghetto uprising. Astonished, dismayed, she wondered aloud, ‘Why,’ she said, ‘are our Jewish brothers doing that? Why are they fighting? Couldn’t they wait quietly’—the word was quietly—until the end of the war?’ Treblinka, Ponar, Bełżec, Chełmno, Birkenau. She had never heard of these places. One year later, together with her entire family, she was already in a cattle car traveling to the black hole in time, the black hole in history, named Auschwitz.

But Mr. President and distinguished guests, these names and others were known to officials in Washington, and London, and Moscow, and Stockholm, and Geneva, and the Vatican. After all, by April 1943, nearly 4 million Jews from surrounding countries had already vanished, had already perished. The Pentagon knew, the State Department knew, the White House knew, most governments knew. Only the victims did not know. Thus the painful, disturbing question—why weren’t Hungarian Jews in 1944—they were then the last remnant of Eastern European Jewry, why were they not even warned of the impending doom?"
