"There is a more hawkish perception among virtually all circles in Israel" than there is in the United States, said Yossi Alpher, a consultant who has worked with Americans for Peace Now. "It's very natural. Iran doesn't say the U.S. has no right to exist and doesn't do the equivalent of denying the Holocaust. It doesn't deploy proxies like Hamas and Hezbollah against the United States and on its borders.""We don't think crippling sanctions are right if the meaning of that is that the sanctions will not be targeted against Iran's governments and leaders, but will target Iranian people," said spokesman Ori Nir. "We think that's not only morally wrong but strategically perilous."In a policy statement, J Street says it does not oppose further sanctions "in principle," but "under the current circumstances, it is our view that ever harsher sanctions at this time are unlikely to cause the Iranian regime to cease weapons development." Engagement should "not be conducted with a stopwatch," it said.
