Where does the united Stand in regards to Israel - Either for or against. One cannot burn both ends of the candle and not get burned.

So God told Abraham that who blesses him (and his descendents) He wil bless:

There are three  statements made within the Divine promise of blessing given to the descendants of Abraham, Isaac and Jacob. 
The first is that God will bless those who bless the Jews.  When the United States wrested its seat at the council of nations from England, it became the first nation on earth to grant full citizenship to Jews.
The U.S. was the first nation to allow the Jews an unrestricted vote. It was the first nation to recognize the incomparable blessing the Jewish people have been to humanity.

The second is that God promised that in the Jews "shall all families of the earth be blessed."  Without the Jews, there would be no Bible. Jesus came to earth as a Jew. Without the Jewish Jesus, there would be no Christianity. In America, the influence of American Jews is hugely disproportionate to their numbers. Conspiracists point darkly to the "Jewish influence" in education, banking, law, medicine, government, media and entertainment as evidence of a Jewish conspiracy to control the world.  The "Jewish influence" in American life is part of God's blessing on America


Finally, God promised that He would "curse them that curse you." The precision with which God kept this promise is awesome.  During the Crusades from 1095 to 1270, Jews in Southern Europe fled to Spain, England, Scandinavia and Eastern Europe as the resulting in  persecution and wholesale massacres of the Jews.  England turned out to be the wrong place to go; in 1290 King Edward I expelled the Jews. King Charles II did the same thing in 1394 in France. Interestingly, ironically Jews found peace and security in Spain and Portugal while those countries were under Muslim rule.
In the 1400s, the Moors were kicked out of Spain by the Papal forces of Europe. In 1492, on the same day Columbus set sail for the New World, Spain expelled any unconverted Jews who had survived the Spanish Inquisition. This time they fled back to England where the Protestant reformation now welcomed them.
Spain's global empire lasted less than a century after it expelled its Jews, to be replaced by the Jew-friendly British Empire whose reach extended to every corner of the globe. In 1917, the British captured Palestine from the Muslims. The British Crown offered the Jews a homeland via the Balfour Declaration, and a year later, England won the First World War.
After WWI, the British broke most of their promises to the Jews, restricted Jewish immigration to the Holy Land, and in the years since have increasingly turned their backs on the Jews that brought the British great blessings for more than 300 years.
The British Empire upon which "the sun never set" in 1900, had, by 1948, lost its last colony when Burma declared independence, and the  Empire was no more.
In 1933, Germany was among the most cultured and sophisticated nations in Europe. Old Berlin was Europe's Crown Jewel. The Nazis turned on the Jews, together with most of Eastern Europe, and 12 years later, Europe's Crown Jewel was a pile of burning rubble.
The Arab world, which had been  blessed during its Golden Age, collapsed into its present state of affairs.
The Arab Muslims supported Hitler, opposed Jewish immigration, waged repeated wars against Israel, deny Israel its rightful territory, and now mount a global jihad to finish Hitler's goal of total extermination. The backward nature of modern Islamic culture and society are the fruits of those efforts.
Historically, wherever the Jews were welcomed, that nation flourished and prospered. Where the Jews were persecuted, those nations floundered.
