Economic measures could be a different story, but pulling that lever on an an ally of 75+ years would damage the US's credibility. Not to mention to the domestic impact in the US. I don't think any decision makers weighing national interest would go there.

Iron Dome simply allows Israel to do more offense. Without it, they would need to be more cautious.
