History Sunday Presents: Most Decorated: The Nisei Soldiers. It was on December 8th 1941, one day after Pearl Harbor that the United States declared war on Japan. That was also the start of an undeclared war against many Japanese-Americans. More than 100,000 Japanese-immigrants and their children were taken from their homes and put in relocation centers or internment camps. But despite the humiliating treatment, several thousand young Japanese men desparately wanted the chance to fight for their adopted country. On our program Gerald McRaney tells the story of two combat units made up almost entirely of Nisei: second generation Japanese-Americans. Their loyalty was and patriotism questioned was questioned by fellow soldiers, until the Nisei saw action in Italy and France.
