Ackerman studies his statements on Iran:
How to overthrow the Iranian regime? Gingrich has floated a variety of tactics. Some days, he suggests unleashing bombs and cyber attacks. Other days he thinks all you need are a few radio broadcasts, deniable assassinations, the good intentions of the Iranian people — and, just maybe, the moral force of the leader of the Catholic Church. Either way, Gingrich is promising a reckoning with Tehran. And he’s going to have "so much fun" doing it.
This is the candidate Republicans trust most on foreign policy. Beinart likewise looks at the GOP's rhetoric on Iran:
The extraordinary thing about today’s Iran debate is that being wrong about Iraq has barely undermined the hawks’ influence at all. In 2012, as in 2002, Republicans are driving the political discussion, and in 2012, as in 2002, Democrats are petrified about being seen as too soft. Once again the media, which did not cover itself with glory in the run-up to Iraq, bears part of the blame. To allow Gingrich, Santorum and Romney to saber-rattle on Iran, as they have in debate after debate, without forcing them to confront the consequences of their saber-rattling on Iraq, is professional malpractice.
