Excellent post, thank you!

Axios reported yesterday that, "In recent days, the U.S. military sent several B-2 stealth bombers to the Diego Garcia military base in the Indian Ocean in a deployment a U.S. official said was 'not disconnected' from Trump's two-month deadline."

For this reason, the reasons discussed in the article, and other reasons, it seems pretty clear to me that the primary purpose of the B-2 buildup in Diego Garcia and the orders to deploy the USS Carl Vinson carrier strike group to the Middle East is to counter Iran, rather than the Houthis. And the main focus of any military operation against Iran would be Iran's nuclear weapons program.

Whether any military operation will proceed against Iran is another question, of course. Trump's letter to Ayatollah Khomeini purportedly gives the country two months to complete a nuclear deal, but how much wiggle room will there be? Does the Trump administration plan to attack Iranian sites no matter what, and are they setting the bar unrealistically high for Iran so that they can have an excuse to bomb the country? Will they be able to achieve some agreement that allows Iranian leaders to save face? Or will their terms be too humiliating for Iranian politicians to accept? Given the personalities and political pressures involved on both sides, I think it's a bit more likely than not that the situation will not be resolved peacefully.

The market for "US-Iran nuclear deal in 2025?" is currently at 28%. This means that the market thinks it's likely that either the two-month deadline Trump gave to Iran for completing a nuclear deal is not a real deadline (perhaps starting negotiations would be acceptable), Trump's threat of military action is a bluff, or the US will attack Iran. I do think it's possible that the threat of military action could be ended if Iran starts some form of negotiations that are acceptable to the Trump administration, and Iran could drag those out ad infinitum if given the chance. However, I don't think the threat of attack is a bluff. If the market for "Will Iran close the Strait of Hormuz in 2025" is any indication, it seems likely that the market would think there's roughly a 25%-40% chance that the US will launch a serious attack on Iran. And then I'd guess that the market would think there's an approximately 30%-45% chance (maybe up to 70%, as the Polymarket question goes through the end of 2025) that the US will back off the upcoming deadline, probably as long as some kind of talks are in progress. It's just not clear to me how we can get from the current situation to talks under conditions that are acceptable to both governments and allow Iranian politicians to save face.

It would be close to impossible to complete a nuclear agreement in the two months the Trump administration is giving Iran. So it's not completely clear to me what the Trump administration really has in mind and what's going to happen. But I give it a 60% chance (and posted that near the end of my twitter thread two days ago) that we will see the US attack Iran before the end of April.
