Yeah that didn't work well for Iran in the past either though. When Mossadegh dared to nationalise Iran's own oil, the British set up a naval blockade to stop Iran exporting it and the USA and UK helped overthrow him via a coup.
The west was very happy with Shah Pahlavi, up until the early 1970s when he increased the price of oil and helped Iran gain greater control of its own oil production and pricing. Then guess what, he gets overthrown in 1979. Khomeini was aided into power partly through Jimmy Carter's cackhanded naivety. He was sold this idea of Khomeini being a Gandhi figure in Iran 😆
Khomeini turned around and rebuked the west for their interventionism and sent a strong message that western interventions would not be tolerated. Iran immediately started funding Shia militant groups around the middle east at this point to strengthen their position. During the Iran-Iraq war, the USA supported Saddam Hussein in an effort to bring down the Iranian regime. Which didn't work...
Bill Clinton made some headway in building a better relationship with Iran under its leadership under Khatami. During this period, the US government finally publicly acknowledged its involvement in the 1953 coup. Shortly after 9/11, Iran actually helped the USA in their fight against the Taliban as it was a mutual enemy. However, the IRGC had been undermined the relationship Khatami was building with Clinton by funding regional militias, hence Bush including Iran within his definition of an Axis of Evil. Relations soured during Bush's presidency.
The JCPOA was forged during an era where the Obama administration and Iran under Rouhani made concerted efforts to foster a better relationship. Again, IRGC actions undermined the diplomatic processes however it was the closest Iran and the USA had come to building a better relationship with one another.
Then Trump came along...
The thing is, regardless of whether Iran plays nice or not, its relationship with the west is down to the whims of a few key figures. Generally the pattern has been that Iran has responded better to diplomacy than aggression.
One of the biggest factors against longterm stability (aside from US policy) has been the IRGC.
One tactic to remove power from the IRGC is to help foster an environment where they find it hard to recruit - at the moment it is one of the best paths to social and economic mobility within Iran. It offers salary, housing and benefits that are virtually unmatched by the private sector within iran. Its other appeal is a strong sense of nationalism and social status (many leaders within iran had a background working in the IRGC). Now imagine a world where sanctions are less severe in Iran, the private sector has more wealth, private companies are able to offer salaries, compensation and benefits that are either on par or exceed what the IRGC is offering and in return you don't have to risk your life or independence - suddenly the IRGC would find it much harder to recruit.
Also bear in mind that the majority of people in Iran have repeatedly voted for progressive candidates and are not backing hardliners. I don't think the average Iranian citizen would want to join the IRGC if alternative stable economic routes were available.
I strongly believe that the best way to remove power from the IRGC is to build stronger relationships with progressive figures within the Iranian regime such as Khatami, Rouhani and Pezeshkian and to lift economic sanctions. Over time, the need for a body such as the IRGC and the appetite for it would erode.
What is most definitely not working is Trump's current "negotiating" approach. Launching a war shortly after a series of negotiations where Iran was willing to make concessions and was negotiating in good faith was an awful move. Being under attack often brings countrymen closer together, it invokes a greater sense of nationalism...and oops there we've gone and made recruitment into the IRGC easier haven't we? D'oh!
Let's also not forget that the assault on the children's school was a double tap attack and that those missiles are equipped with cameras to ensure the targets are correct and that they won't cause undue civilian harm. A person reviewed the footage from the first missile, saw that it was a school (or at the very least not an active military facility) and sanctioned a second hit to kill the survivors and rescuers. These are obviously the acts of a nice country that obviously wouldn't be forever looking for opportunities to line its own pockets...
