YOU SAID:
In order to form a more perfect union, to establish justice, to ensure domestic calmness, to provide common defense, to promote the general welfare and to assure the blessing of freedom to themselves and successors, Order the people of the United States. We will enact this US constitution.
INTO JAPANESE
より完璧な組合を形成し、正義を確立し、国内の落ち着きを確保し、共通の防衛を提供し、一般福祉を促進し、自らと後継者に対する自由の祝福を保証するために、米国の人々に命令する。我々はこの米国憲法を制定する。
That didn't even make that much sense in English.
