I suspect the plan was (and still is) to weaken authorities in Iran so that the people take over. Or have the Iranian government reach a deal that would be less favorable to them.
A plan with quite long odds you could rightly say, but not as stupid as subduing them by invading them I suppose.
Who is the people, as opposed to who is in charge now?
After all this, you still believe there’s a plan? At what age did you give up on Santa Claus?
It still sounds like a dumb plan, especially since part of it was the plan to put a hereditary king as new ruler in place - a king that lived outside of Iran the whole time.
And per analysis I heard in French media from Iranian opposition understood the war as a war of destruction, not as a war of liberation. As they continued to be executed daily by the regime.
Meanwhile one of multiple explicit day 1 plans was a plan to negotiate with successor within the regime - recreate the Venezuela situation where you keep the regime, keep its tortures, but put head more willing to give up oil on its head.
Trump explicitly stated that was his aim, for the people to rise up after Trump did a little long distance assassination. The plan is far more stupid than subduing Iran by invasion.
"At 2:30 a.m. EST on 28 February, Donald Trump released an eight-minute video statement on Truth Social, saying that the purpose of the US strikes in Iran was effectively[vague] regime change."
US govt would've been propping someone else to take over if they were serious about that plan
