I think the Isreali’s will not attack until after our elections. I think it is worth the risk giving the Iranians more time on the chance of getting a friendly admin in the white house who will be able to keep the Chicoms and the Russians out of the conflict.
I think the feeling is that Israel isn’t going to take a gamble on that. They are not going to let Iran get to the point where their own military can no longer do the job (using conventional force) and they have to depend on someone else, friendly or not, for their own security.
