I don't know about 9/11, but I know that Bibi (at least publicly) doesn't seem to get along with the Deep State agenda of arming Iran. He and Obama were publicly feuding during the Iran Nuclear negotiations–probably because their Intel is pretty damned good, and they knew Obama was selling them out. Just google "Obama Netanyahu Feud."
Of course, that doesn't say much–Obama publicly condemned Iran while giving them $20 - $36 billion since '13…most of it in cash:
Bibi is one of those "gray" characters–you don't know if he's /ourguy or /theirguy, kind of like Putin and some others. But I think he's mostly /ourguy after Obama, because most of Iran's cash went to fund terrorism. That doesn't mean he's necessarily good–it just means that our goals align.
