To answer your question...yes! If we are hit again, we take out Iran, and with the Israelis help, possibly Syria (and their Lebanese puppets) at the same time. Etc, etc.
My idea was even a bit more widespread and indiscriminate.
Start by nuking Morocco's largest or capital city as well as Islamabad first, and keep moving in towards a big heyday on the Saudi Arabian peninsula. Just make it all a massive parking lot, or use some neutron bombs around the oil-rich regions so we can go in later and get the oil.
