I wonder if humanity was seen as weak, thereby underestimated by the galaxy. The author only said it 3 or 4 dozen times, so maybe they weren’t. Hard to tell.
ground forces were deployed to counter key enemy installations, but you said the enemy never enter earth atmosphere, kinda of hard to have it both ways
You are too verbose. You state the same thing over and over again How many times must you say that earth was underestimated? This was a waste of 29 minutes
