In early September, North Korea had told the United Nations Security Council that it was in the “final phase” of reprocessing 8,000 spent fuel rods unloaded from its nuclear reactor in Yongbyon, north of Pyongyang, and was “weaponizing” plutonium extracted from the rods.
If reprocessed with chemicals, the rods could yield enough plutonium for at least one nuclear bomb, according to officials and nuclear experts in Seoul and Washington. Using the same procedure at Yongbyon, North Korea was believed to have already accumulated enough plutonium for six to eight bombs.
On Monday, the North’s official news agency, K.C.N.A., said that the country completed reprocessing the 8,000 rods two months ago and had made “significant achievements” in turning the plutonium into an atomic bomb.
“We have no option but to strengthen our self-defense nuclear deterrent in the face of increasing nuclear threats and military provocations from hostile forces,” the news agency said.
Okay, then. If I were president of the US, I wouldn't be shaking in my boots. I'd coldly look the Dear Leader in the face and calmly say, "We think you're bluffing."
