> For the most-dominant military power in the world to "whoopsy" run out of weapons because of a low-stakes engagement isn't readily believable.
Sadly, I find it very believable. To build them costs lots of time and money. To use them, not so much. Going low tech might risk more casualties in some cases - and so all the political problems that follow along from that.
We've also seen plenty of wishful thinking from the civilian leaders of the military. I'm sure that in their minds, each strike they launch is surely the one that will finally break Iran, better hit them with the good stuff, shock and awe.
They've also been purging all kinds of top military officers, presumably over culture war issues and insufficient sycophancy.
