US Defense Secretary Jim Mattis said Sunday, that the sanctions imposed on North Korea can only be lifted after Pyongyang demonstrates that it has taken 'irreversible steps to denuclearization," as quoted by the Yonhap news agency.

Despite the fact that the state is being embargoed, Democratic People’s Republic of North Korea has been persistently developing its nuclear capability. Along with technical advances in ballistic missile, nuclear technology has significantly increased the defense potential of Pyongyang. Could this "unique weapon" guarantee North Korea security?

North Korea declared on 10 Sept that it would not be afraid of a U.S nuclear attack, following the biggest nuclear warhead test  in its history since 2006, Rodong Sinmun newspaper reported.
