Because as born again Christians, we believe the Bible identifies the Jewish people as God's chosen race. In the Abrahamic Covenant, God has promised to bless those that bless Israel and to curse those who curse Israel. In this current dispensation of grace and the New Testament covenant, God is now working through the church, but following the rapture of the church, God will once again work through the nation of Israel and the Jewish people especially in Israel. Hence the focus in the Great Tribulation will be centered in Israel and Jerusalem. Since liberal left-wing democRATs disbelieve the Bible, they support the current Satanic efforts to destroy Israel with the muzlim hordes.

Jews here, for whatever reason, seem oblivious to the tenuous condition of the nation of Israel.
Most of the Jews in the U.S. (as well as in western Europe) are secular, liberal, left-wing Jews and that is why they voted 78% for 0dumb0 in both 2008 and 2012 U.S. elections. Their real religion & core beliefs are radical left-wing Marxist ideology, and therefore 0dumb0 could roast & eat a young Jewish girl on national TV and the 78% U.S. Jews would STILL vote for 0dumb0 & the democRATs. Likewise the secular liberal left-wing Jews in this country actually despise Israel and would prefer to see Israel destroyed. With Israel still in existence, it is a constant reminder to their liberal left-wing minds that God is still alive and well, and some day God will renew his covenant & protection of the nation of Israel.
A large number of Jews believed, after the horrors of the Nazi regime and the perceived weak response of the USA to Jews caught in its jaws, that conservatism was more dangerous to Jews than liberalism was. They did not envision, however, that liberalism would embrace the unspeakable.
