When the Japanese live translation goes silent because the translators are too stunned to repeat your Pearl Harbor “joke” to the Japanese PM, you’ve officially reached a new level of diplomatic failure.
Those seconds of silence were the most honest reaction of the day.
@Strandjunker Meh, I don't feel bad for Japan on this one. There are so many war crimes Imperial Japan and Japan today have not answered for: Unit 731 was covered up with US complicity, Japanese conservative politicians outright deny the Nanjing massacre ever existed, or if it did, it was orders of magnitude less than the Chinese claim, still no proper apology for Korean and Taiwanese comfort women.
There's literal war criminals still enshrined at Yasukuni Shrine in Tokyo
