Who de-escalated the 12 day war? Iran did, the "Ayatollahs". Who has a religious decree against nuclear weapons since they cannot be used without massacring civilians? Iran, the Ayatollah, not Israel and it's 3 digits of nukes that it threatens to use all the time.

I don't trust the Iranian government, not for any deeply researched reason but because basically everyone I meet who talks about them says that government is not trustworthy. Some of those people are themselves Iranians, and one told me that the Iranian government is speaking literally when describing the USA as "the Great Satan" (and Israel as the little satan).

But: there is a big difference between "we killed some people while targeting actual military assets" and "this city we levelled, it was full of civilians as well as a handful of valid military assets, and now it doesn't exist".
