The two national mottos of the USA are "E Pluribus Unum" and "In God We Trust". "E Pluribus Unum" is latin for "Out of many, one". Just say E Pluribus Unum and think of a God that you can trust that fits "In God We Trust" and Eureka! You guys are already American. That is Motto Harmony. Can even make it a God that doesn't bother you guys with religious bullshit.
