It was choreographed retaliation, just to save face. Everyone was informed prior to the event, and everyone involved played their parts. The only problem may be that Israel is wanting to improvise and escalate. Notice the retaliation was done during the weekend, while the markets are closed. The Iranian action may be out of the news cycle by Monday morning, so it'll be just a blip for the markets.
However, if Israel decides they want to push the issue, then the dynamics change. Since Brandon told Bibi the U.S. wouldn't assist if the situation is escalated, I think the Israelis will hold off until there's further justification. Leave it to Lyin' Biden to screw things up.
