Koplow certainly thinks so.
Barak is smart enough to see that while Netanyahu is almost certainly going to remain as prime minister after the next election, his stock and popularity have suffered a big hit. Barak at this point is going to do everything he can to put distance between himself and Bibi and try to make voters believe that he and Netanyahu have not been as close as everyone thinks. He is going to seize on any high profile issue, irrespective of its popularity, that creates a contrast with Netanyahu – unilateral withdrawal, dismantling illegal settlement outposts or neighborhoods, prosecuting settlers who build without a permit, etc. – in an attempt to reestablish his street cred with the center and the left, who think he has given cover to Bibi’s war talk on Iran. I am also going to go on record with the controversial call of the day, which is that at some point before the next election, Barak is going to go so far as to quit his post as defense minister. As I’ve written, I don’t think that an Israeli strike on Iran is in the cards at the moment, and that means that Barak’s raison d’être in this government is largely over.
