A long time ago, I read a book where a civilization in another galaxy was watching Earth with worry. Every time Earth would hit some new scientific milestone, the denizens of this other world would clutch their pearls, so to say, until, inevitably, Earth developed the Atomic Bomb.
Now, Earth was TOO dangerous, so, this other civilization did a preemptive galactic strike on Earth…simply because they were worried that Earth would ultimately have the ability to strike them.
Anyone remember this or the title?
