This can also be bad in the long term as it's likely that moderates and people against fascism are leaving the country now leaving behind the extremists and Zionists. The spectrum could shift more to being pro genocide amongst the remaining population and even if Netanyahu is somehow out of the government they might vote in another fascist.
Even if the only people who stay are fascists, the fact that there's fewer of them still weakens the state: fewer soldiers, fewer workers, fewer tax payers, fewer customers, etc etc. "Israel" needs to grow to survive.
