There will never be peace in the Middle East (or anywhere Muslims immigrate) until the Muslim world purges its Quranic texts and teachings of Islamic Jew-hatred, creed apartheid and hate. It’s just that simple. As for the “Palestinians,” I am loathe to sanction the term, as the Jews are the “Palestinians.” Before 1948, there were Palestinians Jews living in the British Mandate of Palestine, and the Muslims were killing them then, too. Palestinianism is a euphemism for Islamic Jew-hatred.
Islam needs a civil war in the cause of humanity. I do not see that as remotely possible. Apart from a small number of stragglers and fantasists, there is no real movement within Islam to change its violent and supremacist tenets. And why should they? They are winning with terror.
