Writing at Tablet, a site friendly to Israel, Tony Badran makes the claim that the US has been an on-and-off ally of Iran. He particularly calls out the two Obama terms and the related third term fronted by Joe Biden.
Badran alleges the Israelis had to "work around" US interference and absolute coercion aimed at crippling their anti-Iran efforts, and gives examples. He believes Iran never was particularly powerful but put up a good front with the help of Obama and his claque.
The thing to hold in mind about the Obamas is that neither Barack nor Michelle have much fondness for the US. It's something they've taken pains to make clear on multiple occasions. Those are views to which they are entitled, but the views don't recommend them as its leadership.
Obama's closest advisor was and is Valery Jarrett. She was born in Iran to American expat parents and learned Farsi along with English as a child. Things she shares with Barack include expat childhood exposure to a Muslim culture and mixed race ancestry.
Obama's fondness for things Persian was obvious while in office. I don't think we realized Israel viewed Obama as a de facto ally of Iran, although in hindsight that conclusion certainly seems plausible. I suppose we were more concerned about his shortcomings as our President.
