Or, you know, Israel has an active stake in not wanting relations between the US and Iran to be smooth and probably doesn't want Iran to potentially have a stable economy. And no, not because they're evil Jews or something. They reasonably view Iran as a threat to their existence, so having the US and Iran be at odd is to their benefit, especially when we will try to hurt Iran's pocketbook. I wouldn't use Israel being happy about the deal over as justification for why we should end it and be happy about it.
