Aluf Benn reports in Ha'aretz that a "source close to the new Administration" predicts that the "administration will offer Israel a
'nuclear umbrella' against the threat of a nuclear attack by Iran...

"The U.S. will declare that an attack on Israel by Tehran would result in a devastating U.S. nuclear response against
Iran." But senior Israeli security sources are skeptical: "What is the significance of such guarantee when it comes from those who
hesitated to deal with a non-nuclear Iran?? asked a senior Israeli security source. "What kind of credibility would this [guarantee have] when Iran is nuclear capable?" A senior Bush administration source said that the proposal for an American nuclear umbrella for Israel was ridiculous and lacked credibility. "Who will convince the citizen in Kansas that the U.S. needs to get mixed up in a nuclear war because Haifa was bombed?"
