"The key question is whether Israeli Prime Minister Benjamin Netanyahu and Defense Minister Ehud Barak will interpret the presidential campaign rhetoric as an open invitation to provoke hostilities with Iran, in the expectation that President Obama will feel forced to jump in with both feet in support of our "ally" Israel. (Since there is no mutual defense treaty between the U.S. and Israel, "ally" actually is a misnomer — at least in a juridical sense.)
As we saw 10 years ago with respect to Iraq, if one intends to whip up support for war, one needs to find a casus belli — however thin a pretext it might be. How about juxtaposing "weapons of mass destruction" with terrorism. That worked to prepare for war on Iraq, and similar rhetorical groundwork for an attack on Iran is now being laid in Israel."
