Well, here you go. The officially licensed novelization of the movie includes the aliens' POV.

That's all it takes. Reading, huh?
Did you read it, Abuhin? Care to share the aliens POV?

No, I haven't read it myself. I can't let myself buy things off the internet right now.
But another site says the aliens call themselves the Regent and confirms their hostile intent.

Search "Battleship YMMV."
Warning - this is an extremely addicting site.
I'll take your word for it being covered at TV Tropes. Every time I go to that site I wind up spending at least an hour there. But it's not surprising, is it? Only someone who is of the mindset that humans can do no right and aliens can do no wrong could possibly see these violent invaders as peaceful and misunderstood. Thanks for the info!
