That's how nukes work. When it comes to nuclear weapons, the world is divided into haves and have-nots. Anyone lacking effective nuclear response can be steamrolled by those who do with total impunity.
The USA has been attacked before but it has never been invaded and forced to fight a war on its own soil against foreign enemies. It's possible that they unconsciously believe war is something they bring to others, never something others bring to them. It's impossible to predict how traumatizing it would be for them if that belief is proven wrong. They could absolutely reach for nuclear weapons if that threshold is reached.

Ukraine begs to differ.
What was 9/11 if not military actions on USA own soils? Like, sure it can be labelled terrorism rather than "conventional military intervention", but psyops apart, on practical level that’s typical asymmetric/guerrilla warfare.
> never something others bring to them
Ever heard of the independence war?
There are gun nut americans who truly believe gun owners would contribute an effective resistance to a modern invading army because they own an ar15. That country is deluded and everyone falls off eventually and trump may have actually accelerated the country out of it's golden age
All the more reasons for Iran to drop their self imposed fatwa on nuclear weapons and get a few.
Iran has been on the receiving end of weapons of mass destruction, chemical weapons by way of US sponsored Saddam Hussain and lost close to half a million of their people. Yet they never for once retaliated with such weapons.
> the world is divided into haves and have-nots
Yes and the most important lesson of recent history is for have-nots to become haves ASAP.
