Kim Yo Jong, the powerful sister and possible heir to North Korean President Kim Jong Un, has delivered a sharp threat to former U.S. President Donald Trump. In her announcement, she clarified that North Korea will not abandon its nuclear program.

Her comments came after recent trilateral talks between senior United States, South Korean, and Japanese officials. The countries reiterated their desire to completely denuclearize North Korea, a promise that has been elusive even after years of negotiations and sanctions.

North Korea’s nuclear aspirations In defiance of strict international sanctions, North Korea has carried out six nuclear tests since 2006 four while Kim Jong Un has been in power. Pyongyang has traditionally justified its nuclear weapons program as a defensive measure against what it perceives as aggressive military coordination between the U.S., South Korea, and Japan.

U.S. authorities have expressed worry that North Korea’s new-generation intercontinental ballistic missiles (ICBMs) would be able to hit the U.S. mainland with nuclear weapons.

Kim Yo Jong condemns U.S.-led actions Responding to recent trilateral meetings, Kim Yo Jong condemned the three countries for doing something out of ‘uneasiness’ regarding the increased military capabilities of her nation.

Via North Korea’s government-owned Korean Central News Agency (KCNA), she declared, “[T]he just know that ‘denuclearization’ of us is nothing but a daydream that can never come true.”

She went on to declare that North Korea’s nuclear power ‘can never be reversed by any physical strength or sly artifice’. She went on to say that any talk of denuclearization not proposed by Pyongyang was ‘the most hostile act’ and a ‘rejection of her nation’s sovereignty’.

Call for policy change Kim emphasized that if the United States, South Korea, and Japan are keen on solving their security issues, they need “to totally abjure their sole unilateral effort at altering the current status quo and rocking the current stance of the DPRK and sincerely seek a way to preempt head-on clashes.”

Although Trump has shown interest in resuming talks with Kim Jong Un—having met him three times during his presidency, there has been no official signal from the Biden administration about restarting negotiations.
