Reeducation camps could have been regional in the beginning, or the different alien races could have divided up the continents before the invasion and therefore be allowed the time to ease their human slaves into the new world order?
Except there was no invasion in the classic sense. The Humans started the war and it was a clusterf*ck from day one. Also both sides liberally used nukes, biological and chemical weapons. I imagine that after 9 years of that the people in defiance mights not want to use nerve gas even if it worked on the attacking aliens. Assuming the people in defiance even had nerve gas. Which seems unlikely.
