What is shaking the public order in Europe's cities today is seething desperation that has erupted in directionless violence. The rioters' targets can just as easily be the government in Paris as other members of the underclass, as was recently the case in Birmingham. And the terrorist attacks in Madrid and London are also fresh in people's minds.

It was merely a coincidence that Queen Elizabeth and British Prime Minister Tony Blair met with the family members of the 52 victims of the London subway and bus bombings last Tuesday to officially mourn their deaths on July 7. And it was also nothing but a coincidence that last Wednesday was the anniversary of the murder of Dutch filmmaker Theo van Gogh by an Islamic extremist. But these highly symbolic coincidences have not gone unnoticed, as evidenced by a recent story in Time magazine that describes a "Generation Jihad" forming in old Europe.

The events in Birmingham and the Paris suburbs are unrelated to terrorism. The riots are not about jihad, Iran or Palestine. But they have given rise to concerns that this urban violence could easily become a breeding ground for terrorist organizations like al-Qaida and other extremist groups.

According to official figures, France is home to a little over 5 million Muslims, the largest per capita concentration of Muslims in any country in the European Union. However, the official count is viewed as unreliable; religious affiliation is not recorded in the French census. France's Muslims feel marginalized, as do millions of other immigrants from former colonies throughout Europe, many of whom are unemployed. They live in suburban ghettos, unable to afford better neighborhoods. Now, with the ghettos turning into battlefields, the notion that immigrants will voluntarily assimilate is proving questionable.

Of course, part of the problem lies in the sheer numbers of immigrants -- and the fact that they tend to live in the same place. Metropolitan Birmingham, Britain's second-largest city, has a population of about a million, and just under a third are of African or Asian descent. Statisticians believe that Birmingham's traditional white majority could become a minority in the next decade. And the same holds true for Amsterdam, now home to about 150 nationalities.

Some are calling this new Europe "Eurabia," a reference to the growing influence of Islam and Arabic culture, despite Europe's political and cultural roots in Christianity. Indeed, one out of 10 Dutch citizens was born abroad. Disneyland near Paris offers prayer rooms for French Muslims. And in Britain, immigrants from former colonies have mostly slipped into the poverty of ghettos.

How can the members of this "desperate and dangerous new underclass," as social workers in Leeds call them, become responsible citizens? Who is preventing them from attacking one another, as was the case two weeks ago in Birmingham?

It doesn't take much for violence to erupt. The recent unrest in Lozells, one of Birmingham's poorest neighborhoods, claimed two lives, 20 injured and a large number of smashed windows and torched vehicles. The violence erupted when young Asians, most of whose parents came from Pakistan and India, clashed with the children of immigrants from the Caribbean.

In Birmingham, the violence was triggered by a rumor that Ajaib Hussein, the owner of a successful cosmetics business, had caught a 14-year-old Jamaican girl shoplifting and then, joined by up to 25 acquaintances and employees, raped the girl. There is no evidence that the incident occurred, nor that the alleged victim exists. But the suspicion alone -- just as in Clichy-sous-Bois -- was enough to ignite the worst violence in Birmingham in more than 20 years, evidence of the enormous tensions in suburbs with a similar social makeup.

In Lozells, home to about 30,000 people, more than half of residents are of Asian origin and 20 percent are Caribbean. The district's 22 percent unemployment rate is almost three times as high as that in the entire Birmingham region. "People here have to fight for every crumb that falls from the tables of the wealthy," says Bishop Joe Aldred.

The violence is fed by street gangs like the "Muslim Birmingham Panthers" and the "Burger Bar Boys," groups that originally formed to protect residents against racist attacks. They have since turned into crime syndicates, and Lozells has become a metaphor for Britain's failed integration and immigration policies, a community that the government can only control through tough policing. Large ghettos have appeared, say experts, and the anger of those who live there is directed at neighbors with different skin colors and bigger television sets -- and not at the "infidels of the West."

Britain's white establishment, warns Trevor Phillips, head of the Commission for Racial Equality, is "sleepwalking" into a future where cities will be full of "black holes." Recent surveys conclude that 95 percent of all white Britons have exclusively white friends, that 37 percent of nonwhite residents also prefer to socialize with their own, and that this trend is on the rise, especially among young people. In places like Lozells, only one in 15 children succeeds in climbing the social ladder.

Such neighborhoods are fertile recruiting grounds for fundamentalists because "the majority of Muslims in Great Britain are frustrated but cannot talk about it," says Sayid Sharif, 37, an immigrant and construction engineer from north London. "They would never publicly express approval of the London attacks, but they secretly believe that Great Britain got what it deserved."

Britain officially mourned the victims of the July 7 bombings just last week. A few days later on the other side of the channel, the Netherlands marked the first anniversary of the murder of filmmaker Theo van Gogh, who was killed by an unemployed Moroccan extremist.

The Dutch also face the ruins of their integration policy, long considered exemplary. Indeed, for American terrorism expert Jessica Stern, the Netherlands is "a laboratory that's especially well suited for studying the development of fear." Stern is astonished at how the murder of a single individual can affect an entire country. "How can a nation suddenly become so consumed by self-doubt? And how can it be that not just the Muslims, but also the native Dutch, find themselves in such an identity crisis?"

Sixty percent of the Netherlands' 1 million Muslims see themselves as Moroccans or Turks first, are often proud of their cultural norms and values and seek comfort in their own communities. This creates parallel worlds so disparate that immigrant children speak of "the Dutch" as enemies. Their siblings attend Koran schools, and more and more Muslim women now wear head scarves in public. Interactions between Muslims and native Dutch are becoming increasingly abrasive, especially in public places like Amsterdam's shopping streets.

The country's journalists, attorneys and politicians of every stripe have been receiving anonymous threats. Even Amsterdam Mayor Job Cohen, named one of Time magazine's "European heroes" of 2005 because of his conciliatory stance, now needs bodyguards. And Dutch authorities are installing more surveillance cameras in the country's most volatile urban neighborhoods.

"We were too soft. The days of drinking tea are over," says Dutch Minister of Immigration Rita Verdonk, who has adopted a hard-line approach toward troublemakers. Her officials have increasingly taken to deporting rejected asylum seekers, including those who were previously tolerated and whose children even attended Dutch schools.

According to statistics compiled by the Anne Frank Foundation, there have been 106 reciprocal acts of revenge since the Van Gogh murder, including the firebombing of the Muslim Bedir Elementary School in the tranquil town of Uden by a youth gang that left behind a clear message to the country's Muslims: "White Power."

The combat zone is expanding, mirroring the scenario pale author Michel Houellebecq described in his latest bestseller. And it seems as if Europe's rootless immigrants are changing life on the Continent in dramatic ways, with Birmingham and the Paris suburbs providing a taste of what may well be in Europe's future.
