Just reading a few tweets its clear that the Israelis say there will be a 'response' to this. It won't be the end of the cycle then.
I know some are saying that we should just concentrate on Irish events etc, but if this turns nuclear it will explode a debate in Ireland about neutrality. They will say we are out of step on that etc etc, I think we should stay neutral, the US federal government is not our 'friend'.
Anyway it means what happens in Israel/Iran actually does have big implications for us, not to mention a possible Muslim uprising in Europe.
