The population would drastically decrease for many reasons...disease, violence, starvation, loss of medical care and drugs, all the older folks in the nursing homes and most in the hospital, the people on Rx to maintain their sanity or helath and a host of other reasons.

All persons in prison or jail for any level of violent crimes should be immediately executed..if not the level of later violence will be quite bad. Do we as a people have the stones for such actions?

The availability of food will dictate the population numbers. Having a food available in the midwest with no transporation to get it to the east coast...or anywhere else means ...no food.

For the people who think their home and property is safe...and they will just hunker down....not very realistic. Most have not faced a dedicated enemy much less a starving, psychotic, diseased, thirsty dedicated enemy.

The food in the hills will disappear rather quickly and clean water will be much more difficult to get, disposal of waste, etc.....the little things we take for granted would become much more apparent. Toilet paper, soap, shoes, clothes, no diapers, feminine pads and such...the list go on and on.

Cash will not be KING.
