The rhetorical components of - ‘Israel could launch attack on Iran unilaterally before November’s US Presidential election’ - scattered across in this piece. 

In a series of interviews with Israeli television stations on Tuesday, Netanyahu said, “Iran wants to annihilate us. I won’t let that happen.” …

Netanyahu, meanwhile, said on Tuesday that “things that affect our fate, our very existence, we don’t entrust to others - not even to our best friends. Obama and Romney both said that Israel has the right to defend itself against any threat, and we are obligated to make the decisions.”

1. Though USA UK EU all must be all vehemently against such attack.
2. Israel’s defense tops are against such attack.

And also, another crucial item this article doesn’t update us about is - 

• Israel’s public opinions/views on unilateral attack on Iran before 2012 USA presidential election.

Last time Haaretz reported on this, I remember there really wasn’t a strong majority supporting such decision.
