The last government that threw their Internet kill switch fell pretty quickly afterward. In the US it would be political suicide.
Not if it was framed as "protection from terrorists."
The politician who figures out how to shut down the internet, albeit temporarily, and claims somehow that it was to "protect against a terrorist cyber threat" would win any election by a landslide.
Even if he was a cyborg.
Especially if he was a cyborg.
In fact, forget the whole internet terrorism thing. I'd vote for a cyborg on his cyborgian characteristics alone.
