could deploy a hydrogen bomb with a yield of one-hundred kilotons by 2020.

Joel Wit,... editor of North Korea monitoring website 38 North, said during a press briefing

in Washington on Wednesday that it was their projection that within the next five years,

the North could have a single-stage thermonuclear weapon that is five times more powerful than

the atomic bombs dropped on Hiroshima and Nagasaki in 1945.

He also forecast the North could make significant progress on a two-stage H-bomb, which is a

larger yield nuclear weapon. The assessment comes after Kim Jong-un recently

claimed his country is in possession of a hydrogen bomb.
