would not a One State solution be the best - when people talk of a 'one state solution', they're usually talking about one state ruled by Arab Palestinians.
There is no reason to believe why such a state would be any good at all. Bye bye gays, atheists, etc.
But, yes, one state ruled by Jews might be best, but so unlikely as to be impossible.
Israel has existed since 1948 - it also existed thousands of years ago, too.
