Berlin ? The crimes seem lifted from a Nazi-era scrapbook: a rabbi beaten with a beer bottle, swastikas painted over Stars of David, a gasoline bomb hurled at a synagogue. But they appear in police blotters across Europe today, disturbing omens of new strains of anti-Semitism.

Intolerance toward Jews is changing. Traditional anti-Semitism is coinciding with leftist opposition to Israel’s response to the Palestinian intifada. And attacks on Jewish institutions in France, the Netherlands and elsewhere suggest that a burgeoning population of frustrated Muslim men is transplanting Middle East animosities into Europe.

This comes as a uniting continent, seeking to assert itself as a global power, wants to transcend the grainy, horrifying images of the Holocaust. Though the continent is an eloquent testament to constitutions and human rights, as Europe reinvents itself, so does the way it hates.

This is a “warning cry, a warning to Europe,” said Cobi Benatoff, president of the European Jewish Congress. “Anti-Semitism and prejudice have returned. The monster is with us again.

“What is of most concern to us, however, is the indifference of our fellow European citizens.”

Government leaders acknowledge that problems exist for Europe’s 1.7 million Jews, although they are concerned that some Jewish groups may be creating unjustified panic. Officials do not want European anti-Semitism confused with the more systematic and politically motivated campaigns waged by groups such as Hamas and al-Qaida.

“We do see attacks against synagogues, desecration of Jewish cemeteries and physical assaults on Jews,” Romano Prodi, president of the European Commission, said recently at an anti-Semitism conference in Brussels, Belgium. “But let us be honest and keep things in perspective. . . . I do not believe that any organized form of anti-Semitism comparable to the anti-Semitism of the 1930s and 1940s is rampant in Europe today.”

The failure to create Middle East peace and the aftermath of the Sept. 11, 2001, attacks have sparked two phenomena in Europe: a rise in anti-Jewish fervor and the mistrust of a Muslim community that has nearly doubled over the past decade to as many as 15 million. In cities such as Hamburg, where several Sept. 11 hijackers lived, the suspicions that Germans harbor toward Islam have created essentially parallel societies, embittering thousands of Muslim men and limiting their opportunities.

One of France’s Islamic leaders, Dalil Boubakeur, urged Muslims and Jews to “pull in their horns” and cooperate because they both face prejudice from ultra-right political groups such as the National Front in France and Germany’s National Democratic Party. The National Front, whose leader, Jean-Marie Le Pen, once described the Holocaust as a “detail of history,” has the allegiance of 16 percent to 20 percent of the electorate.

Statistics on anti-Semitism can be misleading and limited in scope. There are, however, definable trends. Anti-Semitic incidents — including physical assaults, vandalism, hate mail and threats — increased in Europe after the outbreak of the Palestinian intifada in 2000, according to government and independent data.
