Bibi (and the west) wanted regime change
that did not happen. The bulk of Iranians rallied around the current govt. He wanted to eradicate Iran's ability to enrich

There is huge international outcry, just not in the west. One could argue that the consequences of this outcry isnt substantially retaliatory, but there is no doubt major outcry from the global majority and has only strengthened defense agreements among the major powers supporting Iran.
It was already known that the US would aid in Israel's defense, especially considering that this attack was jointly coordinated. So while the US intervened, it was only intended to deescalate, evident by the potempkin attack on Iran's nuclear sites. Bibi's ultimate goal is to have the US involved in a long-term, official military capacity, which it did not achieve.
Trump got the opposite of what he wanted. He completely alienated his base by forsaking his promise to not get militarily involved in West Asian affairs and drag the US into more war. A significant number of his supporters view him as weak in this regard, not a so-called strongman. And what does he have to materially show for his efforts
nada.
This is a victory for Iran because the mystique of Israel has been completely broken by Iranian missiles. Everyone in the region thought Israel was unassailable -- supported by the US with the weapons and forces of the US -- they assumed it was invulnerable. And now it's quite clearly vulnerable and was so at the point of breaking apart, because there are a lot of pressures inside of Israel right now. The myth of Israeli technical, material superiority and exceptionalism has been punctured. This is major.
What impact this will have within the region however, we will see.
I would venture to guess that the unilateral phrasing is referring to the fact that Iran's response did force Israel to turn to the US to intervene and broker a pause in hostility... thus halting Israel's aggression.
They did this without the offered aid from Russia or China. Unlike Israel who started the aggression and required the US to step in on its behalf
