Nuclear Disarmament

[mrmod]

But won't (let's say) 50-100 be enough? I mean we have thousands on Earth. Do we need all of them?

Of course we do. We paid to have them built. We may in fact at some point in the future need them. Lets say for the sake of arguement because lets face it none of us here know anything about nukes except they blow a damn big whole, make a large area of what ever they blow up uninhabitable and we are all scared of them, that there is an astroid the size of jupiter out there somewhere that is on a collision course with earth. It has been for hundreds of thousands of years. We don't know about it yet and we reduce our nukes to 50. How many will it take to blow something that big up or even move the damn thing enough so that when it passes it does not still do bad things to our orbit? Hmmm, well lets say for the sake of arguement it takes 50.
What about the other one we can't see behind it?
To do away with the most powerfull means of defence know to man or throw away most of what we already have is a fools errand. Why, because they scare us?

I see the point you're making. And no, it's because we are far much more likely to blow ourselves to bits than an asteroid, with them.
