From Zvi Barel, in Ha'aretz:
Israel cannot keep up for much longer the role of managing the global coalition against Iran. Its term is running out, not least because, in the wake of the Gaza war, it has lost its status as a country under threat. It may seem that the two fronts are unconnected, but it's hard not to notice how less qualified Israel is to cry wolf as it prevents pasta trucks from entering the Gaza Strip.
Unfortunately, this erosion is spreading. You can't be perceived as a bully on one front and a righteous nation on the other. It's not that the Iranian threat has weakened, it's that the shine of its potential victim has dimmed.
