In reality Romney has produced a very lack luster showing on foreign policy as per the following:
1) Romney Speaks Harshly but Treads Fine Line on Foreign Policy; http://www.nytimes.com/2012/10/09/us/politics/mitt-romney-speaks-harshly-but-treads-fine-line-on-foreign-policy.html?emc=eta1
2) Romney’s Missing Foreign Policy; http://www.nytimes.com/2012/10/08/opinion/mitt-romneys-missing-foreign-policy.html?emc=eta1
3) The World We’re Actually Living In; http://www.nytimes.com/2012/09/30/opinion/sunday/friedman-the-world-were-actually-living-in.html?emc=eta1
Of all of the hands Romney might hope to play the foreign policy one is his weakest. He's done nothing but make mistakes with regard to foreign policy.
