[Does so]

Again - where is any of the evidence that the Japanese military had a sizable segment of Japanese Americans ready to do their dirty work?

Most of the Japanese in Hawaii were NOT interned at all——most of the Mainland ones were.

In the week after the Pearl Harbor bombing, the unpatriotic behavior of the Japanese-descended inhabitants on the Hawaiian island of Niihau, likely added to the angst of the times. Wikipedia, Niihau Incident:

"The [the crash-landing] incident and the actions of [pilot] Nishikaichi's abettors demonstrated the potential for Japanese national allegiance among immigrant Japanese populations to work against the US war effort. This ultimately may have influenced Franklin D. Roosevelt's decision to intern Japanese Americans during World War II."

“This ultimately may have influenced Franklin D. Roosevelt’s decision to intern Japanese Americans during World War II.” “
