As soon as I heard that there were no US casualties, I knew this was pretty much all for show. Plus, it happened after US market hours. I said this in another forum, that you can usually tell when things are real and when they're staged or done for show and bluster. If something happens during US market hours, it tends to be more of in the real category. This is just another North Korea type of thing where both sides get to talk tough and "save face" and no real harm gets done on purpose.
It is interesting, though, that Iran really doesn't seem to care that we killed their general. They say they do, but their actions don't match. Makes me want to put on the conspiracy-that-really-is-more-of-a-not-so-conspiracy hat.
