Dear Sir,
I'm a a member of the imperial intergalactic security forces. We decided that we no longer need to hide the truth and deceive you. Your world is in great danger.
It appears that you have found one of their secret underground missile silos. Communist pigs are ready to eliminate any threat to their plans to destroy the world and unfortunately you have turned on their way. Also, today we got some new photos of that region, made from space. It seems that everything is much more serious than we thought at first.
Personally, i'm gonna to get fucking out from this planet as fast as possible, and I recommend you do the same.
Sincerely, Agent Smith.
