Was it not you spencer who convinced me only a few months ago that it was nuclear weapons that prevented any large scale war, and prevented Russia from taking over Europe? Now you want all nukes gone?
What happens when all the nukes are gone, some tinpot dictatorship manages to build a nuclear program and suddenly they're more powerful than the world's superpowers?
Nuclear weapons prevent wars between superpowers which have enough nuclear weapons to destroy the planet, and they know it.
What I am worried about is the smaller countries, the ones with five nukes, ten nukes. Israel, Pakistan, India, and to an extent, France and England, do not have enough nuclear weapons to kill everyone on the planet. Iran and North Korea seek to acquire these weapons. Some of these countries are no threat, France and England come to mind immediately, but others would gladly use nuclear weapons, such as the first three I mentioned. In the event of a full blown war between India and Pakistan I have no doubts that there would be a nuclear exchange. They do not have much to lose, and their governments are not used to coming to the brink of extermination. They would see only gains out of obliterating the enemy's cities, no losses.
Iran supports terrorism. Who would they give a nuclear weapon in the event that the United Nations began blowing smoke up their ass? Well certainly, someone who could bring that nuclear weapon within 300 meters of the United Nations building in New York City. That would send a message, and it's already clear they would have no qualms with doing something like that.
Nuclear weapons prevent a massive, intentioned exchange between Russia and the United States from occurring, but don't mistake this for nuclear weapons being peacekeeping tools in today's global climate. Proliferation of nuclear weapons gives more and more countries the means to wipe an entire city off the face of the earth with one piece of ordnance. Nothing else is capable of that, no weapon is capable of wreaking such horrible destruction and murder upon its intended victims. The presence of nuclear weapons anywhere is a threat to every living person on this planet.
And just a quick thing to explore: What if Iran and Israel get in a nuclear exchange, or what if Iran decides to back a few terrorists and they wipe New York City off the face of the planet? Either way, at this rate this would be possible in ten years. Iran or Israel could start the first, and terrorists would orchestrate the latter scenario. In either event, the United States would quickly get involved and conduct a nuclear strike against Iran. Of course, with these missiles in the air, nobody would know where they're going, just that they're going in that general direction, so, India and Pakistan would launch against each other. Nuclear warfare is a domino effect, and both sides are weary of each other and their relations with the United States, especially India about US-Pakistani relations post-9/11. So, that would result in several million dead. Delhi would be a crater, and so would Islamabad. Naturally, while this is all happening, and while the nukes are still in the air, China and Russia would get ancy. Russia would launch, not knowing what the hell was going on, and judging on their readiness to launch in 1995 after a Swedish rocket test, they would very quickly conduct an almost unlimited nuclear strike against the United States. After all, there are probably thirty nukes in the air already, and they don't want to feel left out, so they launch a devastating strike, which results in a full launch from US bases. Perhaps China would get involved, maybe lob a few at the US, but probably not, because it would be bad for business. And this is where the world ends, the US and Russia are devastated, probably a few hundred million people dead altogether between India, Pakistan, Russia, Iran, and the US. Fallout would devastate the entire planet, and within months, nuclear winter would strike, killing off the rest of humanity after perhaps... thirty years of survival.
Satellite conflicts really do make all the difference.
