Hamas is Sunni and Iran is Shia. Sunni and Shia don't really matter in these contexts. And if you think Islamist rebels hate Shias more than they hate Israel and the USA, it's a toss-up, imo
The Sunni world is mostly fine with Israel, other than Hamas of course, which is why Hamas had to work with Iran (although it seems like it backfired on Iran)
Egypt, Jordan, UAE, Sudan, Bahrain and the Saudis (through back channels)
It's just a fact, there's absolutely nothing ridiculous about what I said, if anything Sunni regimes are more worried about Iran than israel.
