Why does the United States favor Israel?

Jews began to immigrate to the United States in the17th century. In the old world, they were persecuted and bullied. In the liberal atmosphere of the new world, they gained equal civil rights. Israel has also made outstanding contributions to the United States in the scientific field. Jewish physicists are gifted: Einstein, the founder of relativity, Bohr and Bonn, the pioneers of quantum mechanics; Fermi, the pioneer of atomic physics; Lippmann, who founded the law of conservation of electricity; Michelson, who measured the speed of light; Feynman, who proposed the formula of quantum electrodynamics; Sigmund, one of the discoverers of antiprotons; And chemists, including Movasan who separated pure fluorine for the first time and established high-temperature chemistry; It is also a pioneer in the study of dye synthesis. Haber, one of the founders of ammonia synthesis, has many biomedical scientists: ehrlich, one of the founders of modern chemotherapy, Lanzteiner, who proposed four human blood types, such as A, B, AB and O, and Weiner, the most famous mathematician who proposed cybernetics. Most of these scientists have contributed to the development of science and technology in the United States.

In the political field, according to the proportion of Jews in the population, there are many high-level Jews, which can almost influence the political decision-making of the United States, and the words are very heavy, which makes successive American presidents have to stand on Israel's side. The Israeli-Palestinian conflict is the cross of the United States. The United States defends Israel, but it has also been persistently mediating peace in the Middle East for decades. 1978 Israel and Egypt reached reconciliation, 1993 Israel and Palestine signed a peace agreement and recognized each other, all of which were the results of American mediation. When the United States was involved in this muddy water for half a century, what did other world powers do, and what did Europe, the initiator of the Israeli-Palestinian issue, do?
