Israel cannot launch an attack that would significantly damage Iran's nuclear program but that is not Israel's goal. Israel wants to draw America into a war with Iran this year, before the American elections. The ideal outcome for Israel is to suck Obama into attacking Iran in support of Israel and then getting Obama voted out in November for his trouble. America would get a long term costly war. Israel would be out of the spotlight and could happily pursue settlement expansion and America would elect a president that has already sworn fealty to Israel even before the election. Israelis can get aroused just thinking about it.
