A minority government won't survive a no-confidence motion.
What would deter his enemies from pushing for one are early new elections.
Theres no guarantee they could win them. And Lieberman wont support a Kachol Lavan government dependent on the Arabs.
At the moment, 56 is a lot more than 44 or even 32. As long as Netanyahu and his partners stick together, they can keep power.
So then they do elections again, right? This time the right may vote more and the left less. People get tired of voting like this.
The good news is this slows down gov’t screwing up stuff...this is their version of gridlock and a split congress.
