Concerning the Italians.... The Wikipedia source that you cited explains quite thoroughly the difference between the treatment of those of Italian and Japanese desent... it this way:
All of the interred Italians were in fact not U.S. citizens
at the time that war broke out. By contrast, approximately 60% of Japanese were U.S. citizens
. The remaining 40% were residents, visiting foreign students, diplomats, foreign sailors and Japanese in the process of becoming (but not yet) citizens. If someone were in fact a Japanse citizen, Italian citizen, German citizen (and perhaps others) in the U.S. at the time that war broke out, it seems quite resonable to me to either deport them immediately or inter them (except perhaps for those already seeking citizenship). 60% of the those of Japanese decent were in fact just as much of a U.S. citizen and you or me.
I am German on both sides of my family, but 6th or 7th generation U.S. citizen (having arrived in the U.S. about 1855. Below is some information that I found about internment of those of German decent during WWII. Apparently about 11,000 were interred, a small number of them were U.S. citizens. By contast, approximately 110,000 Japanese (and 60% U.S. citizens) were interred. Apparently because of the very large population of German-Americans in the U.S. at that time, the situation (for them) was handled quite differently (apparently on a very limited, case-by-case basis). I imagine that there were many millions of German-American U.S. citizens at that time.
From your source:
"Italian American internment
refers to the internment
of non-citizen Italians in the United States during World War II. Unlike the Japanese Americans
who were interned during the war
, they have never received reparations.
However, unlike Japanese-Americans, who were rounded up whether citizens or not, only non-citizen Italians were rounded up.
In 2010, the California Legislature passed a resolution apologizing for the mistreatment of Italian residents.
"Indeed, both foreign-born and native-born Japanese Americans and both citizens and non-citizens were interned, though the majority (about 60 percent) were in fact native-born U.S. citizens.
Italian Americans interned under the War Relocation Authority
were not arrested under the Enemy Alien Act, but were simply "persons" removed under the War Relocation Authority."en.wikipedia.org
------------------------------------German internment during WWII
"At the start of World War II
, under the authority of the Alien Enemies Act of 1798
, the United States government detained and interned over 11,000 German enemy aliens, as well as a small number of German-American citizens, either naturalized or native-born. Their ranks included immigrants to the U.S. as well as visitors stranded in the U.S. by hostilities. In many cases, the families of the internees were allowed to remain together at internment camps
in the U.S. In other cases, families were separated. Limited due process
was allowed for those arrested and detained."
"The population of German citizens in the United States not to mention American citizens of German birth was far too large for a general policy of internment comparable to that used in the case of the Japanese in America. Instead, German citizens were detained and evicted from coastal areas on an individual basis. The War Department considered mass expulsions from coastal areas for reasons of military security, but never executed such plans."
