I think Romney would be much more likely to go to war. He has surrounded himself with warmongering types like Eliot Abrams and John Bolton. He wants to project FEAR,and that does not work.
It would be ever so nice if the US could be as evenhanded in the Middle East as it is in South America, where we respect elections and favor equal rights. In the Middle East, we support democracy in Tunisia, Yemen and Egypt. In Libya we will use weapons to defeat oppression, but will not do so in Syria. We support oppression in Bahrein, because Saudi Arabia,another oppressive country, supports it.
That is why we are not assumed to be fair or impartial there. Because we are not.
