iran definitely isn't a western friendly power as a government and is hesitant to US outreach. Not to mention their government has extreme paranoia regarding dissenting, and the hardline elements dont help. however that makes sense with what the US government has done over the years in that country and region specifically in trying to upend their state through malicious means.
I would argue it also makes sense to to a certain degree the anti israeli goverment stance, due to israel's policy positions making it easy to create a narrative of propaganda and hatred against them, even to the point of mobilizing something as morally complicated as hezbollah.
But many people in that country(iran) are fully westernized in their ideals, they have democratic elections and generally speaking are far more of a viable partner in negotiations than somewhere like dictatorially oppressive and anti freedom and absurdly pro terror like saudi arabia which we only get by on because of oil money(we've consistently skirted this issue for years).
We definitely should be trying to get on good terms with them and changing their problematic ways, that would be much better use of our time through things like the nuclear deal pretending they are anywhere near an extreme exporter of terror in the region, especially compared to other nations we could name where that's not conveniently a problem.
