“can anyone give attention to the question, if pali got their own state, and continued to attack Israel, would that give Israel a valid excuse to obliterate their land since it would mean war? Would it be better for Israel to give them a country in that case?”
Just because you are being attacked does not mean you can “obliterate” a whole society.
Also you didn’t mention who would be controlling this Palestinian state. There would be a significant difference if it’s Abbas or Hamas.
