I've often wondered if we should follow the Swiss' example on a planetary scale.
It's not that an alien invasion is particularly likely, but, just in case, we might want to plant a few nukes here and there, in strategic locations. That is, locations selected to make it very clear to any potential invader from the stars that sending an interstellar invasion armada to Earth would be all cost and no benefit.
I mean, we already have all those nukes lying around, ready to blow the planet to smithereens. We might as well put them into use as actual "deterrents".
