Your post shows tremendous ignorance of history.
1.The Jews didn't kill Jesus. The Roman Mercenaries did, and they were more than likely pagan Germans.
2. Jews were some of the earliest immigrants to America. They didn't just come here in the Fifties. They came in the 1600's, the 1700's the 1800's and the 1900's. They are still coming to escape persecution. Iran, alone killed an estimated 10 Million Jews in the past 1000 years. For that Iran needs to be destroyed.
3. We Christians do not support Israel because they were the first. We support Israel because of Biblical prophecy. The Bible had said thousands of years ago that the Jews would be scattered all over the globe because of their lack of respect for Jehovah. Their temple would be destroyed and everywere they went in the world they would be persecuted. Their prophets said it over and over and over again, and then it happened. The prophets also said that just before the end of the Earth, Israel would be reunited in God's Land of Eden (Israel). Within one generation after Israel was reborn, the Messiah (Christ) will come and destroy those who worship Satan and his false Prophet, Mohammed (May He Burn Eternally In Hell Fire).
