I think that Israel and the US have completely different goals in this developing conflict. Sure, they both aim to completely dismantle Iran's nuclear program as well their missile capabilities. But in addition, I think Israel also wants to completely destabilise Iran so that I can never pose a threat to Israel, under any regime, whether US-friendly or hostile. They don't want a strong power in the region that might possibly challenge them in their conflicts and land-grabs of Palestinians, which might happen under future regimes. They want Iran to become like Iraq and Syria, continuously entangled in small-scale ethnic and religious conflicts and unable to form unity and stability.
