Final answer:
Henry is likely worried about the government excluding the Japanese and forcibly relocating them to internment camps under Executive Order 9066, which affected Japanese Americans during World War II.
Step-by-step explanation:
Henry's concerns about the executive order would most likely revolve around the government excluding Japanese Americans and placing them in internment camps. Signed by President Roosevelt during World War II, Executive Order 9066 initiated the removal and internment of about 120,000 individuals of Japanese descent, approximately two-thirds of whom were U.S. citizens, and did not include the internment of Chinese Americans. The order was a direct response to fear that Japanese Americans might be loyal to Japan and commit acts of sabotage against the United States. The internment occurred despite the absence of evidence showing disloyalty among the Japanese American population, highlighting issues regarding racial discrimination and abuses of executive power during times of war.
