Preventing Iran from having a nuke is IMO a good way of preserving peace. The allies tried appeasment and most historians agree that approach was one of the main causes of WWII.



Huge difference here IMHO is that the west has been using this line for 40-50 years. At some point it's not "appeasement" and just "diplomacy between countries with differing values are complicated."

Put another way: if you want to call it appeasement, fine, it has worked for a long time. On the other hand, "peace via war" has a terrible track record.


What if Iran simply didn’t develop nuclear weapons? Have you considered that option?


What if the U.S. simply stopped interfering with other nations[1]? Have you considered that option? But of course, the U.S. can do whatever it wants because of its military might and the fact that it has nukes.

And there's the answer: on the world stage, you’d better be close friends with someone who has nukes, have your own, or be forced into a client state.

Yes. Do not proliferate nuclear weapons. It’s not a big ask.

> you’d better be close friends with someone who has nukes

This is a completely acceptable and reasonable solution. It is how most of Europe operates.

It's a very big ask to not proliferate nuclear weapons, because nukes correlate with sovereignty. You didn’t address that point at all.

> This is a completely acceptable and reasonable solution. It is how most of Europe operates.

US friendship in the case of Iran means a puppet ruler (Mohammad Reza Pahlavi, the last Shah of Iran). And now Europe is in the process of decoupling itself from the US. Not to mention how the US completely dropped support for Ukraine. Turns out relying on an "ally" for defense like this is not such a great idea.

Israel also understands this, and so has multiple nukes in its arsenal. Why did Israel "simply" not proliferate nuclear weapons even when it enjoyed the protection and support of the US?


If I was Iran, or any country on the US's naughty list, I would be trying to build a nuke as quickly and quietly as I can. It seems to be the only way to not get bombed.


If you botch the "quiet" part this seems more of a plan to get bombed quickly.


Probabilities.

Given the track record in the region and the relationships involved, not getting a nuke seamless will lead to getting bombed with almost 100% certainty over a long enough period.

If they botch the quiet part, they'll almost certainly get bombed in the short term, which may or may not lead to the end of the project. But then will almost certain prevent getting bombed more in the future.


Has anyone credible said/demonstrated that they have developed nuclear weapons?

The US clearly does not believe they have operational nukes, or we would not have bombed them today. The actions undermine the official statements.

Put in realpolitik: would it be worth the US spending an Iraq War's expenditure of lives and $3 trillion to prevent Iran from acquiring a nuclear weapon?

Why?

What makes this moment the place where the working approach of the last half-century simply cannot work another day?


If they had already developed them, then we wouldn’t be having this discussion because nobody is going to war with a nuclear armed state.

The question is only, did they have the means to, and was there an indication they were? The answer is yes. They were enriching uranium at levels that go beyond anything non-nefarious. Their lead nuclear scientists were going to be meeting with their ballistic missile scientists (according to the dossier.)

On would it be worth it: nuclear proliferation is probably the most dangerous existential threat that humanity faces that is completely preventable. Iran is the most destabilizing country in the region and the cascade of nuclear proliferation that would occur if they succeeded would be a nightmare. That is easily worth $3T.


If I’m a head of state in a contested region, I would read your post as an urgent appeal to make acquisition of nuclear capability as the top priority of the state.

Nonproliferation via war is not a viable approach.

This reminds me to read more on the game theory aspect of nuclear states. But I do find it fascinating that no nuclear-armed states have ever been in a shooting war. Interesting to speculate whether the Middle East could have seen less bloodshed over the decades if all the players had been armed since near the beginning of the nuclear age.


One often under-appreciated aspect of proliferation is accidental detonation.

It is not safer for more states to have nukes simply because it introduces more variables that are hard or impossible to control.

And accidents/mistakes/miscommunications account for most (all?) of our closest calls with nukes.


I agree with you about accidental detonation and nonproliferation in general.

But it is also clear that enforcement of nonproliferation without similarly muscular enforcement of sovereignty in general creates a huge incentive for proliferation.

If we truly want nonproliferation, it simply follows that powerful nations must stop actions like the Russian conquest in Ukraine and whatever Israel is doing in Iran. Every government at base has an incentive to do everything possible keep bombs from falling on its cities, and a demonstrated nuclear capability is the only proven way to do that in a regime where nuclear powers are allowed to act with impunity.


I think one thing Iran could do would be to stop funding terrorism in the middle east and perhaps also not threaten the complete destruction of Israel while simultaneously pursuing nuclear weapons. That seems to have sent the wrong message by the looks of it.


Conflating things with nonproliferation detracts from the effort to prevent that singular threat. Now we are weighing the global, persistent threat of more nuclear weapons against regional terrorism and proving unable to decide which is more important. This, in a case where by nature of the problem, “both” is not an acceptable answer.

Maybe we are detracting from some regional terrorism at the margins while increasing incentives for nuclear proliferation. I don’t think that’s a smart trade off, but that’s where we are headed.


> Iran is the most destabilizing country in the region

You misspelled Israel, and a reminder that Israel is the only nation in the region with multiple nuclear warheads.

They tried that. Saddam gassed them.


Some people say Iran having a nuke isn’t the threat some think it is.

Doesn't seem to have worked in this case. They did not have nukes, they got attacked. How you explain that? How do these good guys protect them against evil guys if not with nukes?


Appeasement for an imaginary weapons program our own director of national intelligence just said they don’t have.

Copy and paste this nonsense argument for Iraq 3 trillion dollars ago.


[flagged]


Interesting that you have more intelligence on Iran than our director of national intelligence.


Tulsi Gabbard isn’t exactly a high bar.


She does have the combined resources of all of the US intelligence services.


I just wouldn’t put much stock into anything she says about anything.


Why, because she’s not a DNC loyalist / bloodthirsty chickenhawk?


I must've missed the part where Iran invaded Czechoslovakia and Poland.


I think GP's point was that it's better to act now, before Iran does the equivalent of invading Czechoslovakia or Poland.


Israel has been doing that for almost 80 years and they have nuclear weapons.


What would be the equivalent of Czechoslovakia and Poland and this scenario?


Ah yes, like when we prevented Germany from ever being a problem again with the Treaty of Versailles.
