U.S. intelligence officials are pretty sure North Korea can put a nuclear warhead on an intercontinental missile that could reach the United States.
But experts aren’t convinced the bomb could make it all that way intact.
They cite lingering questions about North Korean leader Kim Jong Un’s nuclear know-how.
“I don’t think North Korea has a good measure of how accurate the missile is at this point,” said Michael Elleman, an expert with the International Institute for Strategic Studies.
“They don’t know if the re-entry technologies will really hold up — whether the bomb will survive the trip.”
North Korea has short-range missiles that can hit its neighbors.
