North Korea recently launched a satellite into polar orbit, demonstrating its capability to send payloads anywhere on Earth. The question now is whether they have managed to reduce the size of their nuclear weapons to what their rockets can handle. If so, they are able to threaten anyone anywhere.
What the newspapers fail to mention is that a satellite may itself be a nuclear weapon, patiently waiting for the signal to detonate when it passes over its target. It wouldn’t even have to leave orbit if it were used as a HEMP (high altitude nuclear electromagnetic pulse) weapon. No one would know that the satellite was not just for weather or communications, so there would be no warning at all before a country’s electronics were fried.
On the other hand, when the satellite exploded, our military would know it was the one launched by North Korea, and that nation would be punished. They must realize that, so we can hope that this will restrain them from using a satellite this way.
