No. It's much worse. Possession of a nuke is akin to constantly pointing a million guns at millions of people simultaneously. Desire to own a nuke is akin to desiring to point a million guns simultaneously at a million people perpetually. Except you must also take note that in the case of the nuke, you need only pull one trigger, as opposed to pulling a million triggers.
Actually, it's even worse. It's akin to putting one bomb each in 100,000 homes, all controlled via a remote control trigger. Actually, it's even worse, due to radioactive fallout. To think that there are people here implying that pointing a gun at someone is worse. And to think that these people are also arguing that a knife in your kitchen drawer is similar.
If you don't understand that, then you you have the logical facilities of a four year old.
If your implying I have the logical facilities of a 4-year old, how about you try this on for size: Let's assume I'm a nuclear bomb engineer. The second I complete my task (the nuke), any one or all of my co-workers automatically have the right to put a bullet in my head (by your logic, it's a threat). That person who killed me, then owns the bomb. The person in closest proximity to him is now the
most threatened, so he kills the newest owner and so on and so forth. This continues on forever until there are no owners of nuclear weapons, but then there aren't any people either, except one perhaps. Seems we just got rid of a million people the same as the nuclear bomb.
We can't say that possession directly implies threat. I know I could own a nuke and never want to use it on anyone or anything. My possession doesn't equate to my intent to use. I may want to use the materials to start a nuclear power plant. But that's just me.
Why do you think the chances of the new owner disarming the nuke to be zero? That's the first fallacy of your silly argument.
The second fallacy: Let's say, that it's not zero, but one in one million, for the sake of argument. Why would each successive owner instead not choose to either have nearly impregnable security guarding the nuke, or more likely, simply not advertise it's existence, thus ensuring no further exchange?
The third fallacy: you assume the nuke is never detonated as it changes hands. But consider if it does. In that case, the total death toll is all that died in your scenario plus the toll from its detonation.
I'll leave you to ponder the second and third fallacies on your own. Let's revisit the first fallacy. You seem to be indicating that the chance of disarmament is zero upon each exchange of ownership. Assuming that to have a grain of truth to it, then it follows that increasing law enforcement would increase the chance of disarmament from zero to some higher number, as that is generally the case when law enforcement confiscates a gun from a criminal who is waving it about pointing it at people. Now, I can hear it coming: you're going to say that increasing law enforcement engaging in the act of confiscation will increase the chance of it detonating as the owner strives to protect his ownership of the weapon. However, if we examine the behavior of criminals, (cartels, etc.), we can see that owners of weapons generally don't discriminate between law enforcement or other criminals when they are being subdued - they will threaten use of the weapon in either case. Therefore, it stands to reason that the best course of action is to limit the proliferation of such weapons in the first place.
