Maybe Obama will send Rodman back. ??
I’m convinced these tests are meant as a demonstration to China, as much, or more than they are meant for the USA, Japan, or South Korea.
Indeed, China has a lot more to lose from a nuclear DPRK than the USA does. They share a border and Beijing is less than 500 miles away.
Such a device is known as a super EMP weapon and is characterized by low-yield explosions on the order of 3kt...very similar to the calculated yield of the devices tested in NK.
According to several press reports, South Korean military intelligence concluded independently of the EMP Commission that Russian scientists are in North Korea helping develop a Super-EMP nuclear warhead. In 2012, a military commentator for the People's Republic of China stated that North Korea has Super-EMP nuclear warheads.
One design of a Super-EMP warhead would be a modified neutron bomb, more accurately an Enhanced Radiation Warhead (ERW) because it produces not only large amounts of neutrons but large amounts of gamma rays, that cause the EMP effect. One U.S. ERW warhead (the W-82) weighed less than 50 kilograms. North Korea's so-called Space Launch Vehicle, which orbited a satellite weighing 100 kilograms, could deliver such a warhead against the U.S. mainland--or against any nation on Earth.
