Remember my post about doomsday scenarios? The one with the EMP pulse going off in your town?
Looks like Congress is thinking about it too.
Except their scenario is much worse -- replace "your city" with "the entire continental US", and you've got the scenario they're talking about.
We've seen how very tall buildings can demolish themselves with a single "disruption". We've also seen how very "tall" interconnected economic systems tend to crush weaker elements with only a small breeze*.
The EMP-above-the-US scenario is not a small breeze, it's a category 5 hurricane.**
"And the rain descended, and the floods came, and the winds blew, and beat up on that house; and it fell: and great was the fall of it." - Matt 7:27
How can we prepare? Work on your year's supply! It will keep you (and perhaps your neighbors) from starving while China and Japan ship us enough electronics to get back moving again.
And it protects you from a lot more than just EMPs -- we never run out of ketchup at barbeques anymore. =)
