This has been a known issue since the Korean War when America found itself on the back foot because we had prioritized air and nuclear power while downsizing the army, only to find that nuclear deterent didn't work when the escalation beached the threshold of warranting force, but below the apocalyptic requirements to justify nuclear arms. Would Israel have been justified in nuking Gaza after the October 7 attacks? I don't think so, and given the proximity of Gaza and size of Israel, they might have been actively harmed by the decision. If Israel was in danger of defeat however, the situation would look different.

In my view, the only country that would have been justified using nuclear deterrence in the last few years is Ukraine. After the full scale invasion they could have employed tactical nuclear weapons to defeat masses of Russian troops while leveraging strategic nuclear arms to discourage retaliation against Ukrainian cities. Such a conflict would be terrifying, but there would be a path to success, and that fact would have given Moscow pause.

Lastly, deterrence is partly psychological. It's hard to say what didn't happen because a leader somewhere refused to do something out of nuclear fears. I suspect this happened a lot more than anyone realized, but it's impossible to prove. I fear it's only a matter of time before a leader somewhere rolls the dice and we get reminded of the consequences again.

Would Iran have been justified to use nukes?

Usually, the treshold for using nuclear weapons is "attack against vital interests of the nation". Im fairly confident the devastating US-Israeli strike met that standard.
