For one I am tired about all this cyber activity against the US et al. I see no reason for this activity to continue without response.....MAJOR, DEVASTATING RESPONCE.
We, the US, could offer our hackers a bounty for bringing down a foreign hacking site or damaging the offending countries digital infrastructure. Fight fire with fire and put our hackers to good use.
Okay.
It should be noted that atomic weapons exploded in space can devastate the electronic infrastructure of a a small nation or continent dependent on yield and height of the explosion. A cyber-war on the USA by Iran would be unwise.
Who would retaliate? Russia would not as we as they have the ability to take each other out.
