I haven't been keeping up with the GOP speeches (I assume you're referring to the GOP nominees), but all I've been able to come up with is Santorum mentioning Iranian nuclear sites, and only if they weren't open for inspectors rather than some sort of display of machismo. Are there others I've missed?
At a couple of the debates, basically everyone except Paul was competing as far as how badly they wanted to bomb Iran. I'm hoping that they weren't serious and were just cynically talking about killing lots of people in order to get a good soundbite for the rubes, but it's scary any way you interpret it. It's like these people are totally disconnected from the fact that they're talking about war.
EDIT: Here's an account of the exchange I was thinking of, Paul made the extremely controversial statement that he wasn't in favor of starting a war, and they all piled on him immediately. The fox news guy said he "jumped the shark" by not advocating immediate war.
