No disagreement there, if you look at "sanctions" then yes, there have been none of relevance for a very long time.
I guess "tolerable" has more than one meaning, so I should have checked which one was intended before starting my previous comment with just plain "No", but before reading your reply I hadn't considered that.
The lack of sanctions is due to how power works rather than anyone else agreeing with them in any specific case: the USA has got too much of the money that everyone else wants, and too many weapons which everyone else wants pointed in the right direction rather than to find they're now standing in a position to read the sign saying "front towards enemy" with a wire trailing off to a nearby bush.
This does not change that it was incredibly stupid for the US to attack Iran in particular, so stupid that it cost the US a significant part of its own matériel, made the remaining matériel less scary as a threat, and reduced the economic relevance of the USA's money, all at the same time.
Every US leader before Trump made sure to not damage those things, and thus retained both hard and soft power. Trump's throwing both away rapidly, at such a pace that it's no longer inconceivable that the rest of the world will be able to sanction the US without fear of what retaliation may result. Consider that Trump's poor choices mean in particular that the EU got away with telling Trump to take a hike over Greenland, and China got away with telling Trump to take a hike over tariffs. With the kind of damage he's doing to the USA's power, this shift may be shockingly sudden when it does happen, with nobody being able to see exactly how close the transition is even 12 months before the world order changes. (I am not saying this is 12 months away today, I'm saying nobody will know even when it is 12 months away).
So, stuff is shifting today specifically because of the USA's "reckless interference in other countries", with emphasis on the "reckless" part. There is a degree of governmental tolerance for the "interference" part, out of fear, meaning the condemnation (such as it is) is somewhere between "toothless" and simply not joining in with the misadventures. Trump appears to be trying to punish every nation who didn't help him attack Iran, but between them and all the nations the US failed to defend from Iranian counterstrikes are rather a lot of nations who are all now looking to each other for military and economic collaborations.
It may not look much on paper; it remains to be seen if it is much in practice. China will of course be happy to substitute for the USA everywhere, but for the rest of us this changes which hyperpower we find ourselves forced to kowtow to, this time less metaphorically and more literally. Reasonable chance a lot of nations make their own nuclear deterrents either way, with all the extra risk that comes with. I didn't want to predict anything past 2031 even before all this geopolitical rifting started.
