The origins of prejudice against dual nationality stem from war and the desire for certainty regarding who can be trusted when lives are at stake. If that is true, there seems to be little if any need for such prejudice in times of peace.

The deep symbiotic relationship between the U.S. and Japan has, long since, outgrown the need for such preparedness. So, keeping it in play is dishonorable.
