Trump orders cuts to South Korea joint drills despite warnings of North’s growing battlefield experience

President says move is based on ‘very good relationship with Kim Jong-un’ but US military officials have said Ukraine war is boosting regime’s combat capabilities

Donald Trump has said he is scaling back joint US military drills with South Korea aimed at deterring North Korea, despite military officials from both countries warning that Kim Jong-un’s regime was learning new battlefield tactics from the Ukraine war.

The drills under Ulchi Freedom Shield, one of two major annual exercises held by South Korea and the US, start on Monday and run until 27 August.

They were expected to involve about 18,000 South Korean troops, alongside US forces and personnel from 11 of the 18 member states of the United Nations Command (UNC), the multinational body that oversees the 1953 armistice that halted hostilities of the Korean war.

However, on Sunday evening, the US president said he was “not happy” with US participation “based on my very good relationship with Kim Jong-un”. He added that they were costly and “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 added that it was too late to cancel the drills so he had ordered the defence secretary, Pete Hegseth, to “substantially reduce” them.
