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

If it didn't matter then all the arab nation would all be aligned, but it matters and they aren't. The Saudis vs Iran is still driving a lot of the faction movement in the region.

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)

I feel like you are intentionally saying ridiculous things, so really no point in talking. The idea that "the Sunni world is mostly fine with Israel" is such a ridiculous idea it's not worth discussing further with you.

Ah, lets see, Sunni countries with diplomatic relations with Israel:

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.
