Zionism

A quarter of the global followers of jesus say, other religions can get to heaven too. But zionism doesn't proselytize and convert them to christianity. Zionism is just supporting the jewish people cause the bible says to but if you believe that jesusis the only way to heaven, why aren't you trying to convert them to your belief system? I don't get it. And i've always wondered about the great commission, if they believe that a good jew is going to heaven or not.
