One of the few countries in the world where Jews who sought haven were accepted and even welcomed was the USA. The very first entity in the world that accepted Jews as equals and gave them the vote was the tiny state of Rhode Island. In Newport one can visit the Touro Synagogue, the oldest synagogue in the US, where they have the famous letter signed by George Washington himself proclaiming that Jews will be given equal rights.
Yet this is all insignificant when the populace decides to act out of racial hatred against Jews. I experienced a few such acts myself when I was living in the US and was active in pro-Jewish activities. An Italian Catholic secretary uttered an anti-Semitic remark to me and when I organized the first meeting of the American Scientists for Peace in the Middle East someone inscribed a swastika on the blackboard before the meeting. I removed it before people arrived. But, these were minor incidents compared to the current wave of anti-Semitism. Bomb threats called into dozens of Jewish Community organizations and Jewish schools throughout the US, large numbers of tomb stones overturned, defaced and smashed in Missouri and Philadelphia.
Many attribute these acts of anti-Semitism to the election of Pres. Trump and the supposed freedom that this has given to right-wing extremists. But, Pres. Trump himself and VP Pence have gone on record strongly against such actions. Pence even spent time with his sleeves tolled up repairing tombstones in Missouri. But, at the same time the Democratic Party has moved further to the left and the fact that Keith Ellison, an open anti-Semite and anti-Israel activist, could have been elected the chairman of the DNC and was appointed as his deputy by the winner Tom Perez, shows where the Democratic Party is headed. For anti-Trump liberals to assign blame only to the Republicans for this outbreak of anti-Semitism is hypocritical.
Anyway, it is clear that anti-Semitism is alive and well and living in America and the conclusion of many Americans, especially young ones, is to become Zionist and make aliyah. Some have predicted a wave of immigration from the US. As a former US resident and current Israeli I hope that is true. What Israel needs is another 50,000 young Americans. That would be the best answer to those anti-Semites.
