Good food for thought.

Back at the height of Cold War, the Soviets had spec-ops teams specifically trained for that kind of work. I suppose there was an equivalent in the US as well.

In the 70's the entire US and Western European infrastructure was still fairly "mechanical". These days, it's all about fiber optics and electronics. I wonder just how much damage you could do now, targeting the fiber optics/communication system.

I'm sure most of us could survive a few days without power, water, traffic lights and whatnot. But the remaining 98% of the population would be in serious trouble, not to mention the economy. A pretty freaky proposition once you think of it.
