Recently Senator Biden spoke with Shalom TV and stated that, "There is this inextricable tie between culture, religion, ethnicity that most people do not understand…You don't have to be a Jew to be a Zionist, I am a Zionist." 
"Christian Zionism is a contradiction in terms…Zionism deviates from the heart of the New Testament…Christian Zionism is adding fuel to the tensions between Muslims, Christians and Jews…If the Christian Zionists' agenda is realized, it will mean the death of Palestinian Christianity in the Holy Land…Zionism is militarizing the church…Christian Zionists overwhelkmingly supported the war in Iraq and continue to support oppressive Israeli measures in the West Bank…the slaughter of [1,255,026 Iraqis*] goes virtually unnoticed and unchallenged because of their belief that President George W. Bush is a dedicated Christian who is carrying out the will of God…The 'blind spot' of Christian Zionists is the fact that the Palestinian people, every day and in every aspect of their lives are living under an oppressive military occupation…Unlike the prophets of the Old Testament Christian Zionists have no prophetic words of reprimand for the State of Israel." 
But Christians who understand that God is love and who strive to practice the Beatitudes, have a few and "Love is not the starving of whole populations. Love is not the bombardment of open cities. Love is not killing......Our manifesto is the Sermon on the Mount, which means that we will try to be peacemakers." -Dorothy Day
Zionism began as a nationalistic philosophy that developed among European Jews in the 19th century which aspired to create a safe secure homeland for Jewish people.
Christian Zionism is an extremist movement which supports the claims of those who believe that the State of Israel should take control of all of the land currently disputed between Palestinians and Israelis. It views the creation and expansion of the modern state of Israel as the fulfillment of biblical prophecy toward the second coming of Jesus.
Christian Zionism is also a modern theological and political movement that embraces the most extreme ideological positions of Zionism, thereby becoming detrimental to a just peace within Palestine and Israel.
