Israel is already a “binational” entity with Jews and Arabs. The change that they’re proposing to make leads inevitably, quickly, and violently, to the elimination of Jews from that equation.
“Palestine”, as currently constituted, is theoretically an entity consisting of Muslims, Christians and Jews. How’s that working out?
Since 1950 Christian population has declined from 15% to 2%, so not so well for Christians. Don't know how many Jews lived in the areas under palestinian authority before the 1948 war, but after, is was zero.
