IRT HapaGuy, and the Asian, Blacks, and Native Americans were fighting the Nazi's and Japanese.  The Asians, Blacks, and Native Americans were all just Americans, and presented a very special lesson in WWII, they all bled red and were all Americans.  The American government policies changed after WWII accepting all born in the United States as Americans.  Then in 1952 came the McCarran/Walter Act allowing the Issei Japanese, who adopted America as their Country, and sending their son's and daughter's into combat to become Naturalized American citizens.  Some 40,000 Issei's from about 1954 to 1964 became Americans.  I remember my grand-mother holding the American flag in 1960 after the swearing in and how proud she was after sending three son's into three different Wars.  And, remember some 110,000 Americans were interned in camps because American leaders did not trust them.
