we brought many points up, i think they were surprised that we knew. reporter: sources say during the talks kim made the bold offer to dismantle the main site of his nuclear program in exchange for sanctions relief, but trump apparently wanted more. experts say north korea has at least one secret nuclear plant that the kim regime has never acknowledged but that trump reportedly said must be shut down. this complex called kang song just outside pyongyang could be the place president trump was referring to based on its layout, heat signature and its security. former u.n. weapons inspector david allbright and researchers at the middlebury institute, believe kim s regime is still producing crucial material for nuclear bombs. at kang song, they re using gas sentcentrifuges, rotor asse, spinning part inside and producing weapon-grade uranium for nuclear weapons. the sigh mte may have 6,000 or
because some of that production could be actually increased if the existence of one secret facility can be confirmed, right? reporter: that s right, wolf. experts who monitor north korea s nuclear production with satellite images and other intelligence, they tell us they believe north korea is operating at least one top-secret uranium enrichment plant. kim s regime has never acknowledged the plant exists, but former weapons inspector david allbright says if it does they could have up to 50 nuclear weapons in the stockpile. thank you very much. . coming up, breaking news as a top gop aide says the president has managed to screw up his campaign message with explosive rhetoric on immigration, the president is doubling down, claiming he could send up to 15,000 troops to the border with mexico and insisting he can change the u.s. constitution by himself. plus, a cnn exclusive. we are learning how the president blamed his own former white house counsel for the
expanding their nuclear arsenal and have been doing that for five years. joel of the u.s. korea institute made a similar assessment in february, along with the institute for science and international security headed by former weapons inspector david allbright. their alarming report warned kim jong un is beefing up his nuclear weapons stockpile at warp speed. worst case, they could end up with a hundred nuclear weapons by 2020. but now china, north kraeps ae ben factor is trying to reflect growing concern over the north korea threat. the chinese are being realistic and understand that a growing north korean nuclear threat not only has implications for the united states and its allies, but also has implications for china. 2 frightening new chinese estimates are even more concerning given this warning by a top u.s. military official this month. north korea, he says, is now
weapons grade material to make an atomic bomb in as little as a month. national security correspondence is live from the pentagon taking a closer look at this report. why is this new report giving this time line? essentially it s significant because it comes from one of the top u.s. nuclear website, a former iaea weapons center. he monitors iran s nuclear program as closely as any non government group in this country. their conclusion released last week, iran could produce enough weapons grade highly enriched uranium in as little as a month. that s vastly shorter than what the obama administration has repeatedly said it would take iran a year to have enough uranium for a bomb. we ve been hearing those estimates for years now. david allbright, former weapons inspector, concludes iran would have to eliminate more than half of the 19,000 centrifuges to extend the time it would take it to build a bomb to six months.
not going to be stopped by other means. david allbright, always good to see you. thanks for coming in on this sunday. thank you. responses to our twitter question, with four months left before the election what else do you want to hear from the candidates coming up after the break.
