Kim Jong Un's Sister Slams US Nuclear Deal, Threatens Escalation as Biden Promises 'End of Regime'

Kim Yo Jong, the powerful sister of North Korean leader Kim Jong Un, criticized the new US-South Korea defense agreement and threatened increased military action in response.
President Joe Biden promised Pyongyang's regime would end if it launched a nuclear attack on the US or allies, and the US plans to send nuclear submarines to South Korea.
North Korea has fired nearly 100 missiles this year and is expected to increase tests of nuclear-capable systems like submarine-launched ballistic missiles.
Kim Yo Jong called Biden "senile" and South Korean President Yoon Suk Yeol a "fool" for trusting the US.
Experts warn the escalating tensions and threats could lead to dangerous miscalculation.
