Alex Stamos talked about this a bit on TWiT late last year:
"It's getting hard to not be conspiracy minded here. They closed CSRB, destroyed CISA. CISA has no confirmed director. This just adds to kind of a complete surrender at least on the cyber side. We are spectacularly poorly prepared right now for a cyber attack."
Hopefully there's still MAD (mutually assured destruction). That is, the US has (I presume) a rather formidable array of cyber offensive capabilities. Anyone thinking of cyber attacking the US might find that concerning - hopefully concerning enough that they decide that an attack isn't worth it.
I mean, I'd far rather that that US had both offensive capability and a solid defense. But the situation is not totally hopeless - or so I hope.
