What made North Korea’s weapons programs so much scarier in 2017

If the higher estimate is true, that would mean that North Korea has a bomb almost 17 times the size of the one that was dropped on Hiroshima, Japan, in 1945.

.. David Wright, co-director of the global security program at the Union of Concerned Scientists, said he believes that the Sept. 3 bomb was a “real H-Bomb” — suggesting that North Korea wasn’t lying when it said it had created a two-stage thermonuclear device shortly before this test. If this is true, it shows that North Korea has now mastered the more complicated technology that entered the U.S. and Soviet arsenals in the 1950s after the first wave of nuclear weapons.

.. Such a device dramatically increases the damage that could be inflicted on a city. It also could mean that North Korea’s missile systems can afford to be significantly less accurate when used in a real-life attack because the blast itself would be so much bigger.

.. After failed tests in 2016, North Korea appears to have shut down the Musudan program and replaced it with something better.

.. In just one year, Cotton said, Kim Jong Un has unveiled six new missile systems. In contrast, his father, Kim Jong Il, tested only two new missiles during his time as leader, and North Korean founder Kim Il Sung tested three.

.. North Korea could probably build up to a bigger event: what has been called the “Juche bird,” a test of a missile loaded with a live nuclear weapon, probably above the Pacific Ocean. “A lot of folks in the U.S. have said North Korea still lacks the capability to put it all together,” Cotton said. “North Korea has made several statements suggesting they think they might need to show us once and for all that they do have that capability.”
