I agree with you, mostly. My read is that Twelver Shi’ism is not a unified hierarchy, and a marja’s fatwa normally binds that marja’s own followers rather than all Shi’a, so your institutional point is broadly right.[1][2] It is too strong, though, to say the anti-nuclear position was simply “invented for PR”: Khamenei did publicly describe it as a real fatwa.[3] At the same time, Iran’s enrichment posture _does_ fit the description of a threshold state, with large stocks of uranium enriched to 60%, so it is fair to say the ruling also had strategic and diplomatic value.[4]

The parts I would soften are the specific claim about Sistani having a significant following inside the IRGC, which MIGHT be true but is much harder to substantiate publicly (although, maybe you have some behind-the-scenes knowledge?), and the certainty of motive. Still, your last sentence is basically right: these rulings are not _immutable_. After Ali Khamenei’s death, Iran’s foreign minister said (quoting the Reuters article), “fatwas depend on the Islamic jurist issuing them,” and added he was “not yet in a position to judge the jurisprudential or political views of Mojtaba Khamenei…” This reinforces the point that doctrine can shift if the leadership chooses.[5]

Strategically, it seems like a dumb move. Right now, Congress is unlikely to approve Trump’s request for $200B to fund the war effort. But if Americans can be convinced that Iran could somehow hit American cities, they would call their members of Congress in a heartbeat and that money would presumably flow without interruption.

Why time the medium range missiles now? It seems like yet another own-goal for this desperate and poorly coordinated regime.
