I have not thought of globalism as meaning a single world government, but rather a world where no government interferes with the progress of global corporate entities.
Perhaps the world corporate entities that imagine they can call the shots would look a lot like a world government.
However I agree this has nothing to do with Judaism.
I was reading some article the other day, and they spoke of globalism in terms of the UN agencies being in charge of the world’s activity in their particular area. It seemed to me to be just a short step to promoting everything being combined under one global UN government.
