The following quotes are from Major General Aharon Ze’evi Farkash, former Israeli Defense Forces intelligence chief

“An attack is not a single strike and once it happens we are in a whole other world. Iran will pull out of the [nuclear] Non-Proliferation Treaty…..and it will be clear that they need a bomb now so that we cannot attack them again. This means that Israel will need legitimacy to be able to maintain the operation with more attacks within weeks, months and years after.” 

“Israel without legitimacy will not be able to, over time, maintain the results of a successful attack.”

“I think that within this window it is difficult to imagine that something will happen a month before [U.S.] elections.”
