If anyone thought last week's visit to North Korea by basketball star Dennis Rodman might have tempered Kim Jong-un's actions, Thursday’s broadside against the United States put an end to that notion.
The reclusive country threatened its enemies with the possibility of, "a preemptive nuclear attack." Even by North Korea’s bombastic standards, this was incredibly provocative.
Last month, Pyongyang had threatened to pull out of the armistice with the U.S. and South Korea that ended the Korean War back in 1953.
The international community reacted to this and especially to the North's third nuclear test last month, as it always does, with yet another round of apparently crippling sanctions. Though, this time Pyongyang's closest ally, China, is on board. But will it enforce them? And has China finally tired of its wayward ally?
In the video above CNN’s Christiane Amanpour puts those questions to Ambassador Christopher Hill, the former U.S. envoy to Seoul and the designated U.S. envoy to the North's nuclear file.
“They haven't been able to take a nuclear device and put it on a missile that we're aware of,” Hill told Amanpour. “There's no sign that they have any kind of deliverable nuclear device. So I would take this in the category of bombast.”
