The sister of North Korean leader Kim Jong Un has criticized the United States and South Korea for proceeding with their annual joint military exercises at a perilous moment for global security. Kim Yo Jong also warned that any challenge to the North’s safety would bring “terrible consequences.” Her statement on Tuesday came after the allies began their 11-day Freedom Shield exercise and while Washington also is participating in an escalating war in the Middle East. Kim didn't directly refer to the Iran war in her statement. But she said that the U.S.-South Korea drills undermine regional stability at a time when wars are breaking out "due to the reckless acts of outrageous international rogues.”
