One of the related risks to a nuclear attack is an EMP blast. Rather than detonating the nuke at ground level and thus destroying infrastructure and human life, the bomb is deployed in the atmosphere, and an EMP blast results. In the former scenario you’d be dead immediately; in the latter, many would die slow deaths, widespread panic would result, and terror would take a drastic toll—all because people wouldn’t have access to their machinery and gadgets that enable them to do all of their basic, day-to-day activities.
Just think about all the things you do on a daily basis that require electricity: turn on the sink to brush your teeth; get in the car to get groceries; withdraw cash from the ATM; refrigerate your food; use the internet to follow the news; call your parents; turn on the lights at night. All of these simple, daily tasks require the electricity we enjoy in abundance today.
