In the midst of the recent U.S.-Israeli tumult, a curious conventional wisdom is starting to evolve. A Washington that cajoles Israel on its settlements and resumes the peace process in earnest may finally garner Arab support for dealing with Iran’s nuclear menace. Although pressuring Israel to restrain its settlements may be a sensible means of gaining constructive Arab participation in the peace talks, it is unlikely to affect the region’s passive approach to Iran. Indeed, should Tehran perceive fissures and divisions in U.S.-Israeli alliance, it is likely to further harden its nuclear stance.
