Jonathan Clark: Then you're going to invade us.
The Alien: Oh, no. No, our moral code does not permit us to invade nor to destroy any form of intelligent life. We are prepared to lend you a weapon, a weapon which will permit you to destroy yourselves without harming your planet. This weapon affects only human life. Nothing else will be harmed. It will be loaned to you for twenty-seven of the thirty-five days remaining to us. If at the end of that time, midnight of the twenty-seventh day, Greenwich Time, you've not used it, the weapon will automatically become harmless. You are under no compulsion to make use of the weapon.
