"...destroyed most of the orbiting satellites communications systems..."

If satellites are taken out, I fear that communication with friends and relatives would be the least of our worries. No satellites means that you can not buy fuel at most/all gas stations, and it might mean that you can not even buy a burger at McD's, or a six pack at your local stop 'n rob. Seems that their computer systems, which they need to be able to run their cash registers/ordering systems, are tied into sat's somehow. If that were to happen, bad things, a lot of bad things, would start, and only get worse with time. In that case, we might have to hire Kevin Costner to be The Postman...
