You notice the story says an Obama aide.
Plausable deniability for Obama.
Also Israel refuses to speak of it, meaning they have some things they consider secret,even if Obama wants to kick the feet out from under Romney with this little leak.
Romney should take credit for this, as well as for the security deal Obama signed Friday. Something like "if I wasn't putting pressure on the Obama administration, this wouldn't have happened". Kinda like Obama touting his stimulus "imagine how much worse it would have been had I not blah blah blah"
