He can’t possibly in any way think that there will ever be a world without nukes. It doesn’t even make sense to say that. What will happen to them? Where will they go? What on Earth is he talking about? Lord have mercy on the US.
They will disapear because you will destroy yours and I will destroy mine. Then there will be no nukes.
Really. Trust me.
I would not lie about a thing like that.
Hopefully, they'll go towards turning South Korea's DMZ into beachfront property.
Realistically, they'll go nowhere. As few as 100 nuclear weapons could render even the largest of nations into a poisoned, medieval basket case for centuries. That threshold is far lower with most nations.
What President Obama doesn't understand is that the prospect of making your enemies extinct, or turning their land into a poisoned, medieval basket case for centuries, is a very attractive prospect within human nature. With a little guidance, that urge can be civilized and suppressed, or it can be fed and nurtured, but either way, it exists.
Getting rid of the weapons is pointless. Even if you destroyed them all, the knowledge to create them cannot be uninvented. Someone could recreate them, and eventually, someone will.
There are a few scenarios on how to exist in a world with nuclear weapons. None of them sound good; none of them are good. Obama's scenario, on the other hand, sounds nice, but is completely impossible.
The only possible answer is global dictatorship.
