This combined with production of perhaps 150 kg of highly enriched uranium may have allowed North Korea to increase the number of weapons in its arsenal by between five and seven, the Stanford report said. US intelligence is not certain how many nuclear warheads North Korea has. The Stanford experts said it was their assessment that "North Korea cannot deliver a nuclear warhead with any measure of confidence to the US mainland," although Hecker said its nuclear weapons were a real threat to Japan and South Korea. Hecker said it was understandable that North Korea should have continued its weapons work, given that it had reached no specific agreement in the latest talks with the United States to stop that work. He said before the talks they would include discussion of corresponding steps North Korea has demanded.
