The evidence was powerful: the Allied powers--the United States, England, the Soviet Union--had not gone to war out of compassion for the victims of fascism. The United States and its allies did not make war on Japan when Japan was slaughtering the Chinese in Nanking, did not make war on Franco when he was destroying democracy in Spain, did not make war on Hitler when he was sending Jews and dissidents to concentration camps, did not even take steps during the war to save Jews from certain death. They went to war when their national power was threatened.
