A couple questions:
If all the power were to go out permanently (other than off grid) would there still be some way for people to get the fuel from the gas stations?
If every major city on earth was attacked, and there was no power and no phone communication anywhere on Earth, how long do you think it would take for governments to organize relief and/or military efforts, and where would they focus them?
Where would they get the gas to power their vehicles?
How would they talk to each other?
If the power went out at your house and never came back on, what would you do? (no phones or internet either) How long would you wait before you would try and go somewhere to see what was going on? Where would you go?
...I appreciate your thoughts.
