Mostly the balance of power.If you don't support getting rid of old nukes, why do you support preventing new nukes from being made? I'm just curious.
Look at who has nukes. We have: stable western european countries, the USA, the main western ally in the middle east (israel), two very stable eastern states (china and japan), and Russia, which is also fairly stable (this mattered in the cold war, mostly). Oh, and Pakistan and India, who both never should have been allowed to develop a nuclear program. EVER. Seriously, that's our next big threat to world peace. Maybe India, but dear god if Pakistan, and even moreso both at the same time having nukes doesn't scare me ****less. Oh and North Korea? See Pakistan
Now look at that. We have every major monetary power in the world. All of the most important nations. Israel is a little out of place, I suppose, and Pakistan and North Korea are WAY out of place, but it becomes very hard to take someone's nukes away from them with force due to MAD once they have them. When all of the powerful and wealthy countries have the nukes, who is going to wage a war against them? Nobody. It's a suicide mission. There can be no world wars without the armies of the USA, German, Russia, China, at least not on a large global scale.
However, the less stable the region where the nukes are in is, the more they go from "keeper of world peace" to "holy **** abu-shimsalabimsbams is gonna blow us all sky high".
Basically, if a region is fairly wealthy, very stable, and not explicitly genocidal, then fine, you can have nukes. However, the more nukes in circulation, the worse...
