Was the United States justified in interning Japanese Nationals and Japanese-American citizens? Why/Why not?

Question

 What was the basis of Hitler and Stalin’s non-aggression pact?

 

Thank you for answer two questions. 

Answer 1

At the time, i.e., following Imperial Japan's attack on Pearl Harbor and the United States' subsequent entry into World War II, a conflict the scale of which this country and the world had never before seen, there certainly appeared to be sufficient justification for the U.S. government's policy of internment for reasons of national security, at least in the opinion of many Americans. However, in the decades since, this Japanese internment policy has been roundly and justifiably criticized as an unnecessary overreaction and a gross violation of human and civil rights, and the U.S. government has recognized its responsibility for the injustice.

 

The non-aggression pact between Hitler and Stalin opened the way for Nazi Germany's invasion and conquest of Poland, precipitating World War II, by assuring that the Soviet Union would not react militarily to Germany's incursion in this country on its western frontier; indeed, the U.S.S.R. participated whole-heartedly in the division of Poland by invading from the east and thereby acquired a sizeable proportion of Polish territory. The pact moreover gave Hitler the assurance that he would not--for the time being, anyway--have to worry about war with the Soviet Union in the east as he proceeded with his plans to invade and conquer most of the rest of Europe to the west of Germany.
