That's what NK launched into space in February. It wasn't just a test satellite. It's small but potent and contains 5 tactical orbit-to-surface nukes, each with a 500 kiloton payload.

This is why NK has adopted a totally warlike rhetoric. They may be outgunned and outnumbered but they have unlimited firing range. Detonated above the US/Europe/Asia/Japan they'll be able to knock out the electrical grid and begin their own ground invasion of South Korea and Japan, leaving Europe and the US to China.

Trust me, this is the absolute truth. My uncle is a general in the British army and they are trying their best to keep a lid on this to prevent worldwide panic. Apparently Obama is "looking at all the options" whatever that means.
