From the Wikipedia article I’d cited:
Historian Gordon Prange notes that "the rapidity with which the three resident Japanese went over to the pilot's cause" troubled the Hawaiians and added: "The more pessimistic among them cited the Niʻihau incident as proof that no one could trust any Japanese, even if an American citizen, not to go over to Japan if it appeared expedient."[16] Novelist William Hallstead argues that the Niʻihau incident influenced decisions leading to the Japanese American internment on the continental United States. According to Hallstead, the behavior of Shintani and the Haradas was included in an official Navy report dated January 26, 1942. The report's author Navy Lieutenant C. B. Baldwin wrote: "The fact that the two Niʻihau Japanese who had previously shown no anti-American tendencies went to the aid of the pilot when Japanese domination of the island seemed possible, indicate[s] [the] likelihood that Japanese residents previously believed loyal to the United States may aid Japan if further Japanese attacks appear successful."
So, this incident, according to historians, is cited as the reason for the internment. Yet, in museums dedicated to the Japanese American experience, this isn’t mentioned anywhere.
So, I’m not saying it justifies sending almost the entirety of the Japanese American to internment camps. Im saying that it was a major justification on sending almost the entirety of Japanese Americans to internment camps, and that information is being repressed in favor of a narrative that the internment was entirely due to racism.
