I partially disagree. You left out a biggie:
Take out Iran’s refined products supply. It is a relatively easy job, in and of itself. The country would collapse within a couple weeks.
That in and of itself does not get rid of the IRGC. First, we need to convince our Gulf State “allies” that they will be forever used as a bargaining chip by Iran’s threat to hit their infrastructure, water and oil, and they likely WILL be hit anytime the existing Iranian regime thinks it needs to remind them. Then, “everyone together now”, reduce Iran’s missile and launcher numbers as far as possible. If we had the Ukie style drones in Ukie style numbers, production of 10 million in 2026, or more, this could happen faster, but, DOD fumbled that ball, so we’ll have to do it the hard way.
Then take out the refined products and initiate the other measures you listed.
Sure, that would bring them down faster, but it would be at enormous and long suffering cost to the Iranian people. It would take them years to restore production.
If it is required to get rid of the Mullahs, then we should do it, but it should be a last resort.
Also, I bet a lot of people would freak out on the world markets because of that sudden and long term loss of the Iranian output, and like it or not, the World Markets have an impact on our domestic policies.
I personally think we should do the right thing regardless of how it might hurt us economically, but I very much doubt that sentiment is shared in the circles of power.
