Before the war started, they thought they could mobilize the protesters by just whacking some top officials. That failed.

Then they thought that they could mobilize the usual proxies like the Kurds against Iran. Unfortunately, the Kurds have been used and dropped multiple times in history already. And they see what happens to a US proxy in Ukraine. So it failed.

Now Hegseth has fired the top general and replaced him with a loyalist. Probably the previous general opposed depleting all stock piles for the Führer's great vision.

Most likely: After 48 days Trump will declare "mission accomplished", retreat, leave the FUBAR situation in Hormuz to other people and prepare for the next grand excursion in a year or so. While his cronies are selling US oil and gas to the EU morons.
