I think the reason for the resolution Israel is getting pressured heavily into accepting the 2 state solution with the West Bank. Israel always claimed to support and work towards it. But this was a ruse, only used to mislead people with false claims of Israeli goodwill.
My guess is that now that even Hamas said they were open to a 2state solution, Israel has to admit they never wanted to agree with a two state solution. Else a two state solution might start to be implemented.
This is not a Netanyahu problem. Every Israeli politician voted in favor of blocking Palestinian statehood. Only the Arabs in the Knesset voted against the resolution.
