You can draw a very neat line between the number of jews currently permitted to live peacefully in palestine vs the number of muslims living within israel.
its not complicated, confusing, unclear or opaque.
River to the Sea means to end the israeli state, and the end of that does not have a happy ending for any jews living on that land.
The end of Israel as an exclusionary apartheid state does not have to mean the end of Jews living there, in a pluralist state guaranteeing equal access to Christians, Jews and Muslims to their holy sites and shared ancestral homeland.
How do you see implementing that politically? What constituency is there?
