What was one consequence of the Attack on Ellwood in early 1942?

The Attack on Ellwood, which occurred in February 1942, was significant as it represented one of the first attacks on the American mainland by enemy forces during World War II. This attack heightened awareness and fear among the American public about the vulnerability of the United States to further attacks, particularly on the West Coast. The incident contributed to a prevailing sense of insecurity, leading citizens and government officials alike to worry about the potential for more extensive assaults on the mainland. This fear was exacerbated by the proximity of Japan's military actions in the Pacific theater.

The other responses address different impacts that might have been related to the context of World War II in California, such as increased military presence or actions taken in response to perceived threats. However, the immediate consequence that resonated with the public consciousness was the fear that further attacks were possible on the U.S. mainland, marking a dramatic shift in American attitudes toward national security during this time.
