All this adds up to a much larger surface area. It's like we're in a stone throwing fight and one side is living in a glass house and the other side is in a mud hut. Losing a cyber war could destroy governments and economies in the West. Imagine no electricity everywhere, no water, no sewer, no planes or trains, no tv or internet. It would be an apocalypse. The same thing happening to Iran might be difficult, but mostly annoying. I'm not sure. In North Korea most people wouldn't even notice.
I can imagine people in Iran reading this and quite strongly disagreeing.
