I don't think Iran is ready with its nuke yet, and I don't think there'll be any more escalation of this. It may mean hanging Hez out to dry, but what Iran is obviously planning on is having a UN resolution come in and rescue Hez, which is exactly what's going to happen. Thus Hez won't really be hung out to dry, just a little embarrassed, and they'll start up again as soon the coast is clear.
Iran will strike when it can, but it's not ready yet. Iran probably didn't expect Israel to respond, and Hez certainly didn't expect it. So they're not really ready for a devastating blow - IMHO.
