A flaw in the military's thinking

When writing my novel, Double Trouble on Corned Beef Row, I had to familiarize myself with military strategy and means of attack and defense. One of the problems I had in writing the book was planning a covert operation to capture an Israeli secret weapon. I had to come up with a scenario that was not only viable but tactically sound. It took me a good while to come up with a solution to my problem, but I believe it was not too far fetched. I was not trying to write science fiction, but a military operation that was unique and plausible. Several people who have read the book have commented on its reality and my knowledge of the processes. Which brings me to the point. I believe the US military has placed far too much emphasis on technology. A single, well placed nuclear device could cripple all of it. A nuclear device exploded in space above the USA could knock out our entire infrastructure from cell phones to traffic lights to water supplies and sewage treatment. If a rogue organization wants to destroy the United States, that is all they would have to do. No more computers, television, automobiles, trains, airplanes, electricity of any kind. The explosion would cause an electromagnetic pulse or EMP that would wipe out anything that uses an electronic circuit to control it from cars to wrist watches. And an ICBM would not be necessary to do it. A rocket launched from American soil by domestic terrorists or smuggled in by enemies could do it, and the military would have no defence against it. Technology is a wonderful thing, but too much reliance on it could kill us all.
