The only way this makes any sense is if Israel is doing what she did during the first Gulf War. Threatening to attack, therefore widening the dispute and dragging the US into a real mess. In that case the US paid Israel to not attack.
The US is being held hostage by Israel. We are committed to protect Israel no matter what she does, and she really doesn’t care about the US.
I would suggest the US do nothing, and shoot down any Israeli airplanes in US controlled airspace. If that were the case Israel couldn’t attack.
