So we nuke Iran, wtf are they going to do? Israel just kicked their ass last week and they snuck off without a word.
You really don't understand how things are done militarily, do you? Israel was responding to a rocket attack that Iran launched against them. They were retaliating for an attack on them.
If we lob a nuke or two at Iran? It's not only going to be seen as an act of war, but Iran's allies are going to step in as well. And, setting off a nuke won't go well with most other countries out there either.
The only way I would ever see a nuclear strike as needed, is if we were attacked FIRST. And, in order to justify a nuclear response, it would need to be a nuclear attack.
