Actually I for one think that Romney would have attacked Iran.
In fact I think that the circumstances in the Mideast would have been completely different Republicans won.
Whether you agree with them or not Republicans generally hold the military in higher esteem then the Democrats and tend to listen better.
I fully believe that the would have been a Status of Forces agreement in place had a Republican been President ( the general consensus is that Obama blew it because of a general lack of interest) as such there would have been a larger US presence in Iraq as there should have been.
Couple that with the fact that there would have been a more robust deployment of troops in line with he general’s requests.
There would never have been a timeline given for the US withdrawal.
The above facts on the ground would not have allowed the rise of ISIS to begin.
In addition during the “green revolution” American support for the opposition would have been clearer and possibly include covert arms from the nearby forces which possibly would have brought down the Iranian government as it brought down others.
The reason is simple
All of the Mideast countries would have supported it (unlike the embassy move) and any one with a half a brain understands what is already being said.
This agreement sets off an arms race in region already teeming with millions of armed individuals calling for the destruction of the US led by a country that Obama’s admits remains committed to the same goal.
Even without Israelis interest’s it is an epically bad decision to basically allow you enemy to become you equal.
