“On Truth Social, Trump wrote: ‘Based on my very good relationship with Kim Jong Un, of North Korea, I am not happy with the fact that the United States has, long ago, agreed to participate in Joint Military Exercises with South Korea’.”
” ‘These exercises are not only costly, with much of these costs paid for by the United States of America (as usual!), but send a signal that is totally inappropriate and hostile, to a Country that, as long as Donald J. Trump has been President, has been unthreatening and respectful,’ Trump wrote.”
“Trump said he had recently asked President Lee Jae Myung to join the US in the ‘Denuclearization of the Islamic Republic of Iran’ but the South Korean leader had declined to help — a situation Trump suggested was ‘somewhat related’ to his decision to reduce the joint military exercises.”
