Ben-Gvir is trying to outflank the rest of the Likud party. He is not getting the support he needs from his own party.
The coalition is in a state of disarray, and it will take time to get it back on track. The fight is not over, it is just a matter of time before the coalition is back on its feet. The battle is over who will be the leader of the coalition in the next election, which is due in 2015.
