This author suggests a number of physical world responses to cyber threats:
These options may seem extreme; they were once unthinkable. But, frankly, so was Russia's playing a major role in a U.S. presidential campaign. If we don't want to suffer more extreme injuries at the hands of our adversaries, we need a few unthinkable responses of our own.
This is in line with my longstanding view that JDAMs are the ultimate cyber weapon [link fixed]:
Let me just say as I long have argued that while cyber warfare takes place on the Internet, until virtual Artificial Intelligence lives online, the equipment and people waging it live in the real world:
It is necessary to prepare for war in cyber-space with sophisticated cyber-weapons as have been deployed against Iran. But in the rush to fight in cyber-space, don't forget that a physical smart bomb can simply blow up a room full of enemy cyber-warriors if they have an office park and we know the address.
Indeed, as I note in that post, offensive cyber-war capabilities at the strategic level might be a waste of effort on our part.
