I give the Senator from Massachusetts a more dramatic and classic example of why the free world is secure today. Why is it secure? Because the United States has primacy in nuclear and thermonuclear weapons. This country is the bastion of freedom and liberty in an imperiled world today because of its primacy in that field. In 1939 Niels Bohr. a Nobel Prize winner. and a great Danish scientist. came to the United States to meet Enrico Fermi. here as a refugee from Italy. His wife was a Jewess. He refused to return to Mussolinis Italy after receiving the Nobel Prize in 1938 because she was subject to persecution in Mussolinis Italy.
