We are entering a phase of extended cyber war.

For the past 30 years we've been in peace time.

If your system got hacked, you could fix it and get back to normal relatively quickly.

Hacks were relatively expensive and hard to pull off.

In wartime, you get knocked off your feet, and then before you get back on them, you're knocked down again.

You'll be relentlessly hit every night, and you very well might not survive.
