As evolved beings, we are here to study the human way of life and do everything to make it a little more difficult than it was before.
We are aware that the allies have penetrated your military and that they have a plan to use your foolishness against you, we just don’t care.
…or something like this:
After you annihilation we plan to have a party on Earth as we aren’t affected by what you call radiation.
As unevolved beings, you need to realise that there is more to the world than just the left hand side of the brain.
