What factors led to general public acceptance of japanese internment?

One of the most controversial actions taken by the United States government during World War II was the early 1942 relocation of about 110,000 people of Japanese ancestry living on the West Coast and their internment for much of the duration of the war in well-guarded, isolated camps farther into the U. S. interior. Likely only the U. S. atomic bombings of Hiroshima and Nagasaki in August 1945 that ended the Pacific War have generated more controversy than the Japanese-American internments. Approximately 40-percent of those interned were Japanese “resident aliens” (non-U. S. citizens, although many had lived in the United States for decades); but the majority, about 60-percent, were U. S. citizens of Japanese ancestry.

this isn't a question and if you're going to list things be kind and use commas.
