And the Supreme Leader would also keep his long range ICBM in reserve for use against targets in the US, said Ankit Panda. Mr Panda makes his shocking claim in his new book, Kim Jung-un and the Bomb - Survival and Deterrence in North Korea, in which he considers the history of the Hermit State's nuclear missile programme, the attempts to denuclearise the Korean Peninsula, and the prospects for future conflict. Kim caused worldwide alarm in 2017 with a series of missile tests which resulted in him declaring that he had "finally realised the great historic cause of completing the state nuclear force".
Much was made of his ongoing spat with US President Donald Trump, who branded him "Little Rocket Man", with Kim countering by describing the US President as a "mentally deranged dotard".
For a time, it seemed as if the world was on the brink of a potentially disastrous conflict, not least when a ballistic missile alert was accidentally issued via the Emergency Alert System and Commercial Mobile Alert System in Hawaii, with sirens sounding as a result.
While the situation has appeared to calm down somewhat since then, Mr Panda, the Stanton Senior Fellow in the Carnegie Endowment for International Peace's Nuclear Policy Program, said it would be folly to concluded the threat had receded, given the realities of Kim's reckless battleplan.

"Pyongyang has studied the manner in which the United States fights expeditionary wars, far from home, and learned that these operations are susceptible to disruption if critical logistics, supply nodes, and military bases are destroyed."
Nor would Kim draw the line there, said Mr Panda.
He explained: "To deter further action against it after the first use of nuclear weapons, North Korea likely intends to keep its intercontinental-range ballistic missiles - the ones capable of striking the US homeland - in reserve.

"Because the US homeland would remain vulnerable to a nuclear retaliatory attack, North Korea may calculate that a US president may
