If Israel attacks it will only be selective bombing of sites and the Iranians may respond in kind as they have the missiles to do so. This might be a bit tense but it would unlikely be major or last long. In which case, I think the Coalition would continue for a while but that it would disolve over the following months as public opinion would determine (rightly or wrongly) that Israel did not act alone. Israel will not invade Iran as it does not have the manpower for that kind of large scale assault on such a large country involving several border crossings - minimally Jordan and Iraq and possibly also Turkey.
At this point, I think we are looking at sabre rattling in the hope that Iran is seen to comply with the agreement with the EU, which would largely be acceptable to Washington if adequate inspections are allowed. The danger is that Iran takes the hump and goes for the bomb. This latter option depending on how close they are. Some think that they are already there as they obtained the necessary expertise and equipment some time ago. All a bit of a gamble. They may, like Israel, refuse to confirm or deny their status for years.
