I am sure meir is well informed of irans progress...and yet, is it at all possible that iran may produce a nuclear weapon before dagan estimates? Is it possible that by the time his proverbial sword cuts flesh, there will be a bright flash ? Personally, I think that iran has been sanctioned now for how many years? how long has this conversation been goin on? has iran stopped? have they respected the international community? no...they just get closer and closer... I am quite certain that meir KNOWS that sanctions wont work...and if that is in fact the case, then waiting makes no sense while they harden defenses and activate cells....it makes no sense.
