In a recent turn of events, Donald Trump, former President of the United States, has once again ignited controversy by using the derogatory expression 'Low IQ'. While the recipient of this insult remains undisclosed, speculation is rampant. This incident is the latest in a series of similar remarks made by Trump and serves as another reminder of his divisive style of communication.

In Japan, where politeness and respect are intrinsic to the culture and language, such aggressive public insults, especially from a high-profile political figure, raise eyebrows. Japan values harmonious relations, and such a direct personal attack is generally considered poor diplomacy and disrespectful, fueling public disapproval.

In the US and EU, while political discourse can be confrontational, outright name-calling, especially revolving around intelligence, is generally perceived as unprofessional and unstatesmanlike. Trump's 'Low IQ' remark is emblematic of his contentious presidency, which often sparked criticism domestically and globally.
