Visits to Jerusalem by senior U.S. officials this week reflect a growing concern in Washington over the possibility that Israel will decide to attack nuclear sites in Iran. The Americans are particularly worried about the hawkish line that Defense Minister Ehud Barak has adopted on the matter. They apparently have the impression, however, that Prime Minister Benjamin Netanyahu has yet to come to a final stance on the dispute.
The number of visits that have been made here by senior members of President Barack Obama’s administration in recent months is unusual. […]
Washington, like Jerusalem, appears to be under the impression that Barak will play a key role in Netanyahu’s decision-making. According to various assessments, in the constellation of forces within the senior forum of eight capital ministers, Barak represents the hawkish camp, while ministers Moshe Ya’alon, Dan Meridor and Benny Begin are leading the opposition to an assault at this time.
In a report in the New York Times about two weeks ago, U.S. administration officials were critical of Barak, who has warned against the prospect within a few months of Iran entering a “zone of immunity,” after which it would be impossible to destroy its nuclear facilities. Barak defines the “zone of immunity” in accordance with Iran’s progress in installing centrifuges at the Fordow underground site near Qom, the location of which would make an aerial assault much more difficult.
Okay so Barak means (only) “few months” by “zone of immunity” (the point when Iran’s nuclear enrichment program will become invulnerable to military/air attacks.)
And just yesterday there was a report that thousands of new, advanced model of centrifuges are ready to be set up in Fordow (/Fodow, Qom) underground facility.
Sanction and P5+1 talks - have to bring up result fairly rapidly (and then this week’s IAEA visit, which probably going to produce no new result).
Though it is mostly believed that Israel’s strikes against Iran’s facilities won’t accomplish desired outcomes, and rather it will lead to the opposite.
