The day of reckoning has arrived.

Nazi Germany didn't exist in 1921 you illiterate baboon.

What a pity Yog.
Beside being a terrible detective you also are a terrible historian.

The Nazi party was founded on the 24 February 1920 and Einstein came in the US in April 1921
so it is obvious that Einstein was already aware of the Nazi party.
Sure, Nazi Germany came after that but the seed of hatred toward Jews were already sown.
Knowing this Einstein was against Nazism and Jews in America welcome Einstein in great number.
Very little to do with Einstein as a scientist.

Yet another story which you just pulled from your ass. In November 1919, "The headline of The Times of London read, “Revolution in Science—New Theory of the Universe—Newton’s Ideas Overthrown—Momentous Pronouncement—Space ‘Warped.’”" in relation to the momentous confirmation of Einstein's theories.

And in relation to his coming to New York in relation to the World Zionist Organization, Einstein writes:

"Long before the emergence of Hitler I made the cause of Zionism mine because through it I saw a means of correcting a flagrant wrong....The Jewish people alone has for centuries been in the anomalous position of being victimized and hounded as a people, though bereft of all the rights and protections which even the smallest people normally has...Zionism offered the means of ending this discrimination. Through the return to the land to which they were bound by close historic ties...Jews sought to abolish their pariah status among peoples... The advent of Hitler underscored with a savage logic all the disastrous implications contained in the abnormal situation in which Jews found themselves. Millions of Jews perished... because there was no spot on the globe where they could find sanctuary...The Jewish survivors demand the right to dwell amid brothers, on the ancient soil of their fathers."
~ Letter to Jawaharlal Nehru, Prime Minister of India, June 13, 1947 [emphasis mine]

More on Einstein's views relative to the rise of Hitler. Note that this all occurred nearly ten years after his 1921 visit to New York.

The Nazis and WWII

The atrocities of Nazi Germany began well before the first shots of World War II were fired in 1939. Adolf Hitler became chancellor of Germany in 1933, and five weeks later, the Nazis established their first concentration camp. In 1935, the Nazis issued the Nuremberg Laws: "racial purity" laws that stripped German Jews of their citizenship. Violence broke out in November 1938, when Nazis destroyed Jewish businesses, homes, hospitals, and synagogues, killed nearly 100 and arrested some 30,000 Jewish men in what came to be known as Kristallnacht. By 1939, 300,000 Jewish refugees had fled Nazi controlled territories. By the war's end in 1945, six million Jews and millions of other victims had died in the Holocaust.

Einstein learned of the tragic events unfolding in his former country from his new home in the United States. Only a decade earlier, he had argued passionately against war. But now Einstein recognized that war was the only option.
The Struggle to Defeat Hitler

A Call for Action

The rise of Nazism in Germany during the 1930s—and the conviction that Hitler could be defeated only by military force—prompted Einstein rethink his strict pacifist views. Increasing numbers of Jewish refugees were fleeing Germany, bringing with them horrific tales of Nazi persecution; Einstein, who was also Jewish, left for the United States in 1932.

And more about his fame:

After the war, two expeditions were sent to test Einstein’s prediction of deflected starlight near the Sun. One set sail for the island of Principe, off the coast of West Africa, and the other to Sobral in northern Brazil in order to observe the solar eclipse of May 29, 1919. On November 6 the results were announced in London at a joint meeting of the Royal Society and the Royal Astronomical Society.

Nobel laureate J.J. Thomson, president of the Royal Society, stated: "This result is not an isolated one, it is a whole continent of scientific ideas.…This is the most important result obtained in connection with the theory of gravitation since Newton’s day, and it is fitting that it should be announced at a meeting of the Society so closely connected with him."

The headline of The Times of London read, “Revolution in Science—New Theory of the Universe—Newton’s Ideas Overthrown—Momentous Pronouncement—Space ‘Warped.’” Almost immediately, Einstein became a world-renowned physicist, the successor to Isaac Newton.

Invitations came pouring in for him to speak around the world. In 1921 Einstein began the first of several world tours, visiting the United States, England, Japan, and France. Everywhere he went, the crowds numbered in the thousands. En route from Japan, he received word that he had received the Nobel Prize for Physics [...]

Note that Einstein's scientific ideas made the headline of the London Times in November 1919, two years before his tour of New York.
