WASHINGTON (AP) — North Korea may have successfully produced a miniaturized nuclear warhead that can fit inside its missiles, passing a key threshold in becoming a full-fledged nuclear power, according to a Japanese defense paper and a U.S. media report.
The U.N. Security Council this weekend slapped its toughest sanctions yet on North Korea over its latest test of a ballistic missile that could be used to deliver a nuclear weapon. Despite the rapid tempo of these tests, uncertainty has lingered over the isolated nation’s ability to couple such a missile with a nuclear device.
Those uncertainties appear to be receding.
Japan’s Defense Ministry concluded in an annual white paper released Tuesday that “it is possible that North Korea has achieved the miniaturization of nuclear weapons and has developed nuclear warheads.” Japan, a key U.S. ally, is also a potential target of North Korean aggression.
And The Washington Post reported Tuesday that U.S. intelligence officials assess that a decade after North Korea’s first nuclear test explosion, Pyongyang has produced nuclear weapons for ballistic missile delivery, including by intercontinental missiles — the type capable of reaching the continental U.S.
The Post story, citing unnamed U.S. intelligence officials, said the confidential analysis was completed last month by the U.S. Defense Intelligence Agency. The U.S. also calculated last month that North Korea has up to 60 nuclear weapons, the Post said, more than double most assessments by independent experts.
Officials at the agency would not comment Tuesday on the report. The Office of the Director of National Intelligence could not immediately be reached for comment.
Alarm in Washington over North Korean leader Kim Jong Un’s pursuit of a nuclear capability has intensified in the past month after the North conducted two tests of intercontinental ballistic missiles for the first time last month.
