According to the first paragraph from the excerpts of the majority opinion, what did the u. s. government believe some japanese americans would do if they were allowed to remain free on the west coast?

Good Morning!

The main fear of the United States of America with Japanese residents on the west coast was that these individuals would turn against the US as the country was in a strong war against Japan and Axis forces. This suspicion led many Japanese to be placed in concentration camps. They feared spies and attacks by these individuals, many of them who had already left their country for decades.
