Is the Jewish-American love affair over? This is the question U.S. Jews are nervously asking -- even sober souls not given to hysteria. The evidence is piling up: murder from Pittsburgh to Jersey City, Jews assaulted in West Hollywood and Times Square, vandalized synagogues, the BDS movement, ostracized Jewish college students, the ever-unfriendlier mainstream media. Add anti-Zionism, that veiled cousin of anti-Semitism, and the mob that stormed the Capitol on January 6, 2021, and inevitably, the memories of 20th-century fascism well up. Yet I still believe that "it can't happen here," unlike Sinclair Lewis, who used the phrase in bitter irony as the title of his 1935 novel about the attempted destruction of democracy in the United States.
