For months now, Mitt Romney’s presidential campaign has overwhelmingly focused on the economy.  But as he geared up his candidacy a couple of years ago, Romney opened with an argument heavy on foreign policy. In March 2010, for instance, he published No Apology: The Case for American Greatness, a campaign stage-setter largely based on the idea that Barack Obama was allowing America to slip into decline while bowing and caving to global rivals like China, Russia and Iran. It wasn’t until the recovery sputtered and Obama scored a string of foreign policy successes that Romney adopted a monomaniacal focus on the jobs picture.
