They say that permission to fire Hezbollah's longer-range missiles, such as those could reach Tel Aviv, would likely require Iranian go-ahead.
I thought the Iranians might be keeping the decision to launch on Tel Aviv in their hands. Nasrallah would have ordered the strikes long ago if he had the authority. If there are missile strikes on Tel Aviv it will signal Iran's desire for a wider war in the region.
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.
It most likely will result in attacks on Damascus and Tehran
