The insect Aliens are hostile?

Did she read Terry Lovelace’s books? I think that’s his name. He was abducted, and saw an insect being I think. And US personnel were on the ship. Now it’s possible they weren’t really an insect being, or that the US personnel weren’t really US personnel.

But if what he saw was the truth, why is the US working with hostile Aliens?

And can I get their tech that makes you appear as whatever you want?
