The main stumbling block is likely to be the concept of "denuclearisation" — both sides say they are in favour of it, but there is a yawning gap between their definitions.Washington wants North Korea to quickly give up all its nuclear weapons in a verifiable way in return for sanctions and economic relief.But analysts say North Korea will be unwilling to cede its nuclear deterrent unless it is given security guarantees that the US will not try to topple the regime."We can anticipate at best a bumpy road to the negotiations," Mattis said."As defence ministers we must maintain a strong collaborative defensive stance so we enable our diplomats to negotiate from a calm position of strength in this critical time."
