This is a great story and a standout member of the Science Fiction Canon. Most of Russell's writing gives hope for the human race against the multitudes of aliens who would crush us. (Unbelievably, he took a lot of slack for that) If you love sci-fi you have to read Russell's short stories. If you haven't yet, this story will make you an instant Russell fan.
This is one of my favorite sci-fi novels. I've thought of it many times over the years. The premise is quite simple. If a wasp in a car can cause the driver to have an accident, how much damage can one man do on an enemy planet. It turns out, quite a lot.
