Thats the issue with your mindset, you expect Qatar to just give Iran everything because it was under siege? Should Iran give Russia and China everything because it has been under siege since 2008? I would hope not. And here lies your flaws in logic. And Qatar was far from starving and had other countries (Turkey) helping it. And again simple research will show you Qatari investments in Iran in last few years.
To address your last point Qatar has significantly more sway than a weak Iraq, a leaderless Oman, and a Pakistan that answers to Saudi Arabia. Qatar also has significant sway over Sunni militant groups as well which is beneficial in places like Syria when you need to do negotiations to retrieve bodies of fallen soldiers (to name a small example).
Lastly if you cannot see why IRGC defending Qatar is in Iran’s interest then it’s not a topic worth talking about with you. You are too impatient and expect a Hezbollah to spring up in Qatar overnight. Iran and Qatar share a massive gas field along with Qatar’s geopolitical location on the choke point of PG these two points alone make it worth defending, but the real reasons go deeper than that.
The Qatari project could take decades to come to fruition, but it can be a tremendous ally in the future. Iran offered this same opportunity to Jordan, but the idiot ‘man child king’ over there declined and borrowed more money from Saudi Arabia.
Your post has serious flaws. First of all, Qatar increased her economic partnership with Turkey multiple times during the siege. So, the question that "Why Qatar did not import as much from Iran?" is indeed a valid and important question.
When was Iran under siege? We're under sanctions but realistically, we have one of the world's largest borderlines in the world with two important allies in our neighborhood (Iraq and Turkey) and we were never under siege. If you can't understand the difference between siege and sanctions, talking to you is a waste of time.
On the other hand, Qatar was literally under siege. Had Iran closed her air space on Qatar, Qatar would've had nowhere to go, except a narrow line over international waters in the Persian Gulf towards the East. Even Qataris have said it publicly that they relied on Iran for food and medicine.
Are you seriously comparing a country like Iran with 83 million people and one of the world's largest number of graduates in STEM fields that produces most of the things it needs domestically, including 80% to 95% of pharmaceuticals it needs, with a country like Qatar that completely lacks such infrastructure and human resources and imports even bottled water and ice cream from abroad?
Qatar is a Turkish puppet. You're blind if you can't see that. Qatar has no influence over Sunni militants without Turkey. Again, why do we need Qatar when we already maintain good relations with Turkey? Qatar cannot act independently in the region. It has never acted independently in the region.
I'm sorry, but you're retarded if you think it is in Iran's interest to get militarily involved against Saudi Arabia in case of a war with Qatar. Saudi Arabia will invade Qatar in days, if not weeks. Just like how Saddam invaded Kuwait in less than 48 hours. We're not talking about Yemen, a large land with rural areas, which used to be the poorest Arab country in the region. We're talking about Qataris who have always lived some of the world's most luxurious lives in a tiny country full of foreign workers to do almost everything for them. Good luck convincing them to resort to guerilla warfare against the Saudis.
Even in a scenario like that, I can assure you that Qatar will choose to ask Turkey for military support instead of the IRGC. Qatar will buy Turkish military equipment instead of Iran's. And at the end of the day, if Qatar manages to resist against Saudi Arabia, an unlikely scenario in my opinion because it will fall in less than 3 days perhaps, Turkey will gain the most of it like it happened this time.
Yeah. Qatar is a project like Yasser Arafat, Hamas or Jordan. It will lead to nothing but more money wasted on a country that has next to no economic or long term benefits for us. You also predicted that Qatar wouldn't mend ties with the Saudis soon, but it happened. Qataris will soon embrace Israel and her relations with Iran will be like any other Arab country in the region. But your stupid adventurism for a lost case will have cost us billions of dollars as usual.
