North Korean politician and sister of the supreme leader Kim Jong-un, Kim Yo-Jong, has insulted US President Joe Biden, calling him an 'old man with no future.' Her comments came in response to Biden's vow that any attack on the US or its allies in the Korean Peninsula would result in the end of Kim Jong Un's regime. Kim Yo-Jong dismissed the threat from the US as 'nonsense.' She further stated that Biden was “too miscalculating and irresponsibly brave”. According to South Korean news agency Yonhap, Kim added that Biden's remark may be taken as a nonsensical remark from the person in his dotage who is not at all capable of taking the responsibility for security and the future of the US.
