Was the Japanese diplomat's apparently threatening protest over American immigration policy intentional?
Short answerThe answer treats it as an unintended failure to carry imagery and nuance from Japanese into English during a protest over discrimination against Japanese immigrants.
NotesThe diplomat was trying to change wording he considered discriminatory toward Japanese immigrants. The explanation offered is that poetic imagery and alliteration did not survive his translation into English as intended. This is presented as an unintended effect, without an intention to threaten war. Later examples show how an English word such as "really" can ask for evidence or signal disbelief depending on tone. The American expression "bless your heart" likewise illustrates meaning that cannot be recovered from the words alone. Such examples explain why diplomatic interpretation requires attention to usage and context as well as literal translation.
