Because the whole decade has been a proxy war between the Saudis and Persians.
Why exactly is Saudi Arabia funding them?
Funny thing is it looks like these guys (worse than Nazis in my opinion...) are being funded by traditional American ally Saudi Arabia so we could be looking at an alliance shakeup if America allies with Iran against GCC interests.
Team Saudi (Sunnis): Saudi Arabia, Israel, Jordan, Qatar, Kuwait, Al-Qaeda, Turkey.
Team Iran (Shia, Shia-led and Shia influenced countries): Iraq, Iran, Syria, Lebanon, U.A.E., Yemen, Oman.
This will simplify things
No... U.A.E. and Yemen are not members of Team Iran. Oman is also neutral...
Israel is certainly on neither side as well...
Yemen have transitioned into a pro-Iran side in recent years due to continuous Shia rioting and a very weak government.
Dubai, Abu Dhabi and the other ones are definitely pro-Iran due to a huge Iranian diaspora, local trade dominated by Iranian trade, and the leaders having sided with the Iranians in the past (like Saudi's claim on Iranian islands in the gulf).
The Omani leader is the middle man between the western world and Iran. He is the most trusted Arab leader to the Iranians and is definitely pro-Iran.
No, no, and no...
