I've heard several credible reports that donnie gave Iran a heads up before the attack.  They moved most, if not all of the enriched uranium out before it hit.  Maybe a few centrifuges, too.   Considering the escalation beforehand they've probably been moving stuff out of all nuclear facilities for months.  There have also been reports they were building a new enrichment facility at a secret location.  They may have assassinated the top scientists, but there are hundreds of scientists and technicians below them that can step up, so that's pretty much a wash.

What I've seen and heard is we had 20 MOPs, used 12 at Fordow and 2 more at a second site.  They targeted 6 at each of the Fordow entrances and didn't really damage the structure, just blocked it off.   I can't see our command structure leaving us without those 6 MOPs in reserve, so a second strike is not in the cards.

Retaliation?  They really don't need to hit us directly or with terror cells.  All they have to do is close the Strait of Hormuz and wait.

Now we wait and see what their and our allies do in response.
