proportion of Christians among Palestine’s Arabs has been declining steadily since 1947, when they were close to 10 percent of the population. Today less than 5 percent of Palestinian Arabs are Christians, and their numbers continue to diminish through emigration to the West (mainly from the West Bank—Bethlehem is now a Muslim-majority town). The proportion of Christians among Israel’s Arab citizens is higher, but given far higher Muslim birthrates and a measure of Christian emigration, the proportion of Christians in Israel’s Arab minority is also declining. So the Christian element in Israel/Palestine is negligible and politically irrelevant.
