If you are a "Strangelove" you are at peace the fact that mankind will eventually destroy itself (most likely via nuclear war). You don't doubt or fear the fact that the end is near. You actually embrace it as the natural outcome of innate human folly.

You are dauntless and unflinching.
In short you have accepted the inevitable justice of Armageddon.
