SEOUL/WASHINGTON (Reuters) - U.S. President Donald Trump said on Wednesday that North Korea no longer posed a nuclear threat and his top diplomat offered a hopeful timeline for "major disarmament," despite scepticism at home that Pyongyang will abandon its nuclear weapons following this week's summit.

Trump and North Korean leader Kim Jong Un issued a joint statement after their historic meeting in Singapore on Tuesday that reaffirmed the North's commitment to "work towards complete denuclearization of the Korean Peninsula" and gave U.S. guarantees of security to North Korea.
