Thing is, it's unclear if Israel is or should be representative of all Jews or just of Israelis. Personally, I don't think it is.
Saying Israel is representative of all jews would be kind of like saying Saudi Arabia is representative of all muslims. Both of them are states with a huge influence in their respective religion, but are still "normal countries".
Compare Israel to say, Vatican City state, which is explicitly supposed to be representative of all Catholics.
Now, a hypothetical "Jerusalem city state" would be representative of all Jews, but that is never going to happen.
A better analogy would be to say that Israel is to American Jews as Ireland is to Irish Americans. It is their ancestral homeland. In some way, they are linked with it whether they like it or not. Whether they support the current state apparatus in their ancestral homeland is down to personal choice.
