Question

why did the us government think internment camps were necessary during world war ii?
to protect against discrimination
to protect national security
to improve relations with japan
to improve relations with germany

Explanation:

After the 1941 attack on Pearl Harbor, the U.S. government fueled by wartime paranoia, claimed that people of Japanese descent (including citizens) posed a potential threat to national security. This led to the forced relocation and internment of over 120,000 Japanese Americans. The other options are incorrect: the camps were discriminatory, not protective against it; they harmed U.S.-Japan relations; and they had no connection to relations with Germany.

Answer:

to protect national security
