The USSR acquiring nuclear weapons was the closest humanity has come to complete annihilation. We were one bad day away from extinction during the Cold War. I'm not sure I would point to that as something we should do more of. Not to mention the potential for accidents and mistakes.

I don't think bombing a country should be the first course of action. Diplomatic action should leave no stone unturned. But if all of that fails, it is strategically advantageous and safer for the world to prevent countries from acquiring nukes by any means necessary.

If you set the example that the cost of pursuing nuclear weapons is unbearable, countries will find better things to do, like enriching themselves in more productive ways.

One of things the US could have done to stop proliferation was to actually honor its commitments it gave to Ukraine in the 1994 agreement in return to Ukraine agreeing to abandon their nukes. It didn't. Now a country sees that US is happy to bomb other non-nuclear countries, but not nuclear countries, and they doen't help even when they agreed to. There is exactly one lesson a country will learn from that.

It's a fair point, but I would flip this around a bit:

Ukraine wants nukes to defend itself from Russia (a nuclear power). Taiwan wants nukes to defend itself from China (a nuclear power). Iran wants nukes to defend itself from the US and Israel (both nuclear powers). India and Pakistan both want nukes to defend themselves from each other (both nuclear powers).

Now I don't want to get into a debate that it is really the benevolent Pakistanis fighting off aggressive Indians or vice-versa or that really Taiwan is the aggressor and that China is a benevolent neighbor, or that poor little Israel is just trying to defend itself from Iran, etc. Those regional squabbles mean nothing to me as I don't even care who is the "real" aggressor, all that matters is that you have two nations in conflict, and when there are two nations in conflict, it is not a stable situation to pretend that just one of them will have nukes but the other will not.

The moment one side gets nukes, the surrounding nations they are in conflict with will also want to get nukes. So as soon as the US got nukes, it's rival, the USSR, also got nukes. And as soon as Israel got nukes, it made it inevitable that at least a few regional rivals in the middle east will get nukes.

Trying to prevent this is guaranteed to fail. It does not matter what the government in Iran happens to be, as long as they care about their own survival, they know they need nukes as long as Israel has them. More importantly, attacking the nation before it gets nukes speeds the process of nuclearization along. Dramatically so. For instance, when Israel bombed the Iraqi nuclear power plant, Iraq, which at that time did not have a nuclear weapons program, went full speed ahead trying to develop one. Because it highlighted that they were at risk of being destroyed as nation from a violent neighbor, and so the urgency of developing their own nukes increased. As soon as India got nukes, it became a top priority for Pakistan to get them. If you don't believe that, then you don't understand the world. It does not matter who you think is the bad guy in a conflict, what matters is the asymmetry.

Whatever will be the outcome of this war with Iran, the Iranians now know that getting nukes is priority one. It will happen within a decade, most likely within a few years. The only way to stop this would be boots on the ground and a long term occupation of Iran, which of course no one, not even the US, is capable of doing.

And then Saudi Arabia will want nukes to defend itself from Iran. That's just how this works. KSA will be the next nation to get nuclear weapons after Iran.

Trying to pretend that you can maintain a long running conflict in which only one side has nuclear weapons is incredibly foolish. Obviously this is not going to happen.

> Trying to prevent this is guaranteed to fail.

Most of European countries could have had nukes by now if they weren't stopped by the US/USSR; going by your logic it was inevitable once the UK and France had them the others would follow but they didn't. Of course at the time at least the American leadership was a bit more (forward) thinking than right now.

If you are the only person in the room with a gun, you have a huge advantage. With each additional person getting a gun too the advantage will be less, but it will still make sense to try to stop that process until everyone has a gun, and we are very far from that point. It is actually cheaper to try to stop proliferation than to build your defense with 'everyone has nukes now' in mind.

It's a failure of longterm thinking.

That is a very, uh, idiosyncratic reading of history.

You are conflating the Cuban Missile crisis of October 1962 -- which was the USSR placing nuclear weapons close to the US in Cuba in early 1962, in response to the US placing nuclear weapons close to the USSR in Turkey in 1961, and in your mind you have blended that crisis, which was a close call in which both sides ultimately agreed to withdraw their nukes, with the acquisition of nukes by the USSR 11 years earlier.

Yet when North Korea, India, China, Pakistan, South Africa, or Israel, got nukes this did not set off a crisis, it was the brinksmanship that set off a crisis.

Soon, both major powers in the gulf -- Iran and KSA will get nukes. Odds are this will happen within a decade. There is nothing anyone can do to stop it.

There are too many pressures forcing this to happen, not least of which is the clear understanding that these nations need to have nukes to prevent destruction by the other nuclear powers some of which are clearly hostile to them and bent on their destruction. It's why North Korea, which kept their nukes, is still around, but Libya, which gave up their nukes, has been dismembered. Just as a matter of self-defense and survival this is inevitable.

However what we can do is tone down the rhetoric of nuclear brinksmanship, threatening global war if a rival doesn't withdraw their nukes. That was the real lesson of the Cuban Missile crisis, which you have confused with Russia's 1949 achievement, or China's 1964 achievement.

Since no one is going to disarm their nukes, this is just something people have to live with. Threatening war over this issue is exactly what causes the risk of global catastrophe, not the spread of the technology, which is inevitable.

I never mentioned the Cuban Missile Crisis. You’ve misinterpreted what I said.

The USSR getting nukes in the first place lead to several incidents which were a judgment call away from armageddon. With the benefit of hindsight the correct call would have been to exhaust all options to prevent the soviets from acquiring nukes.

We just got lucky. Whether it was the Cuban Missile Crisis, the soviet early warning system malfunction in Sept 83, or Able Archer 83 in November, there was a lot of dumb luck.

Proliferation will bring the end of humanity. There will be too many actors, too many variables. You can get lucky with 2 actors. You can’t keep getting lucky. The only option is to ensure you don’t have to be lucky.

I assumed you meant the Cuban missile crisis since that is the only tenuous connection that can be made between "USSR acquiring nuclear weapons" and "end of humanity". If you generally meant "any nation acquiring nuclear weapons" then the statement would kind of make sense, but there is no reason to fear just the USSR, and not, say, the US, China, India, Israel, Pakistan, or North Korea. Maybe some information made it into the popular press about the USSR, but it is unlikely that there is something especially dangerous about the USSR compared to all these other nations.

And in any case, the genie is out of the bottle. There is not gonna be a situation in which a small group of nuclear powers endlessly bomb and attack other countries with impunity. The other nations will get nukes to defend themselves against the existing nuclear powers, it's just a matter of time.

Iran had a deal and wasn't working on bombs, according go all US intelligence agencies. It just failed because trump ripped up the deal.

Last year they were getting close to a deal. It also just failed as Israel killed Irans negotiators.

This situation is engineered.
