IRi has support, no doubt but nobody knows to what extent.
For the West, Khamenei would be an amazing trophy to kidnap and a satisfying kill if possible. Trump has claimed back in July he stopped the Israelis from assassinating him, but that was because Trump wanted a "deal". The deal being presented is a surrender instrument and most likely will be rejected, hence even Trump has no use for him now.
Yes, which suits the West and GCC just fine. They need bad guys to sell weapons.
They have already taken this risk and have the strictest security. It's why they go around assassinating everyone else.
Sunnis did nothing over a genocide in Gaza , why would they bother with Khamenei ? The Sunnis could care less, just look at that revolting "board of peace". Long term if Iran and Shias are further radicalized , that fits nicely with the "New Middle East" that Abraham's Accords and Abraham's Shield are building towards. That New Middle East envisions Shia as the bad guys anyway against the civilized, progressive Muslims and their Western/Israeli allies.
To me it all adds up and these other scenarios are a disinformation.
I agree with a lot what you said but i desagree about "Sunnis", let me explain my point of view because
i'm muslim and a sunni :
1. Don't confuse Wahhabism with Sunni Islam.
2. Don't confuse countries created by zionist treaties and that have many Sunnis within them as "Sunni nations." In fact, in the Sunni religion/Islam in general, the notion of "country" as the West implants it today doesn't even exist.
3. There hasn't been a Sunni military front since the fall of the Sultan (1908). Young Turks and Atatürk were already secular, controlled by Zionism/the West, and even banned the veil, Islam in general, and even tariqas.
4. That's why these countries did nothing for the Palestinians, as they are puppet governments of the West/Israel (with the small exception of some politics within Qatar; the rest is all dominated).
5. Present-day Turkey is controlled by NATO, with American and European bases and even a US atomic bomb inside the country; they are hostages.
6- Because the current West is controlled by the Zionist Jewish lobby, every Muslim is portrayed as a terrorist here, in the media, etc. The notion of "progressive Muslim" only exists in the minds of those being manipulated; in the media, every Muslim is a terrorist, and those who obey the US are depicted as uncivilized and weak like native Indians in old americas.
NOTE: I'll try to explain it another way. Brazil is a country currently dominated by the US/Israel. Now imagine that a country like Brazil (which has only 1% Muslim population) converted en masse to Islam and ended up with 70-80% Sunni Muslims. Would it become an "Islamic nation"?... No, in reality, it would be a place dominated by the US and Israel with a lot of Sunni Muslims inside. That's exactly what Turkey, Saudi Arabia, the UAE, Jordan, Egypt, Tunisia, Morocco, etc. are...
