While Rick Santorum adheres (mostly) to his Catholic faith in regards to domestic social issues like abortion and traditional marriage (and should be commended for doing so) he has a consistent history of contradicting not only church doctrine in his foreign policy but reality. Richard Silverstein (a pro-Israel Jew, mind you, in case anyone is tempted to call anti-semite) decries Santorum’s political rhetoric concerning Israel a “fairy-tale” pointing out that Santorum’s claims that all the residents of the West Bank are “Israeli”; those who call themselves Palestinian aren’t Palestinians but Israelis, because there is no such thing as Palestinians; and Israel “owns” the West Bank by dint of war and conquest are all views with no basis in reality or US or Israeli policy but purely made-up ideological talking points pulled out of thin air for purely political reasons.
Of course, considering that one of the largest and possibly most influential lobbyist groups in all of American politics is the American Israel Public Affairs Committee (AIPAC) I can see why Santorum would go so far as to even defy reality for the sake of appeasing the Israeli establishment. There’s a lot of money at stake here.
I urge you to read Silverstein’s full analysis here.
