The WTBTS would say - Ah, told you so!! And then gleefully rub there hands as suffering and misery spread around the globe.
On a more serious note - A number of years ago there was a fuel blockade in britain, only for a few days. The tanker drivers went on strike.
But pretty quickly the fuel pumps started to empty. People had to join a queue to fill the tank in there car.
One afternoon I joined one of these queue's and when I got near the front I saw a group of men fighting on the forecourt because a guy had jumped the queue. Its not that there was no petrol it was just that there was a shortage and it was being rationed, if people were patient and waited 30 minutes or so they would get the fuel they needed.
The wives and kids of these guys were sitting in the cars watching. All a bit scary.
This highlighted to me that when the essentials are taken away - i.e. food, electricity, water, fuel etc humans go into self preservation mode.
