Is there any evidence that the internment of Japanese-Americans prevented a significant amount of sabotage/espionage in WW2?

Obviously it happened early in the war so there's not going to be much evidence of specific events. Did Japanese war planners foresee taking advantage of the large ethnic japanese population on the west coast?

Is there evidence that Japanese internment camps helped the US reduce spying or domestic attacks in WWII? written by u/DBHT14
