"WASHINGTON — Israel carried out a major military exercise earlier this month that American officials say appeared to be a rehearsal for a potential bombing attack on Iran’s nuclear facilities.
Several American officials said the Israeli exercise appeared to be an effort to develop the military’s capacity to carry out long-range strikes and to demonstrate the seriousness with which Israel views Iran’s nuclear program.
More than 100 Israeli F-16 and F-15 fighters participated in the maneuvers, which were carried out over the eastern Mediterranean and over Greece during the first week of June, American officials said.
The exercise also included Israeli helicopters that could be used to rescue downed pilots. The helicopters and refueling tankers flew more than 900 miles, which is about the same distance between Israel and Iran’s uranium enrichment plant at Natanz, American officials said........
Much of the planning appears to reflect a commitment by Israel’s military leaders to ensure that its armed forces are adequately equipped and trained, an imperative driven home by the difficulties the Israeli military encountered in its Lebanon operation against Hezbollah.
“They rehearse it, rehearse it and rehearse it, so if they actually have to do it, they’re ready,” the Pentagon official said. “They’re not taking any options off the table.”"
