Robin Wright in The New Yorker:
On Sunday, just hours after three men launched an assault on London Bridge, British Prime Minister Theresa May stepped in front of 10 Downing Street and told the world, “We believe we are experiencing a new trend in the threat we face.” In many ways, the attack in the British capital, as well as others over the past two years in Nice, Berlin, Stockholm, Paris, and Manchester, actually weren’t all that unique in terms of tactics, targets, or even motive. A century ago, a battered horse-drawn wagon loaded with a hundred pounds of dynamite—attached to five hundred pounds of cast-iron weights—rolled onto Wall Street during lunch hour. The wagon stopped at the busiest corner in front of J. P. Morgan’s bank. At 12:01 p.m., it exploded, spraying lethal shrapnel and bits of horse as high as the thirty-fourth floor of the Equitable Building, on Broadway. A streetcar was derailed a block away. Thirty-eight people were killed; many were messengers, stenographers, clerks, and brokers who were simply on the street at the wrong time—what are today known as “soft targets.” Another hundred and forty-three people were injured.
That attack, on September 16, 1920, was, at the time, the deadliest act of terrorism in American history. Few surpassed it for the next seventy-five years, until the Oklahoma City bombing, in 1995, and then the September 11th attacks, in 2001. The Wall Street case was never solved, although the investigation strongly pointed to followers of a charismatic Italian anarchist named Luigi Galleani. Like isis and its extremist cohorts today, they advocated violence and insurrection against Western democracies and justified innocent deaths to achieve it.
Europe has also faced periods of more frequent terrorism than in the recent attacks. Between 1970 and 2015, more than ten thousand people were killed in over eighteen thousand attacks, according to the University of Maryland’s Global Terrorism Database. The deadliest decades were, by far, the nineteen-seventies and eighties—during the era of Germany’s Baader-Meinhof gang, Italy’s Red Brigades, Spain’s E.T.A., Britain’s Irish Republican Army, and others. The frequency of attacks across Europe reached as high as ten a week. In 1980, I covered what was then the deadliest terrorist attack in Europe since the Second World War, when a bomb, planted in a suitcase, blew up in the waiting room of Bologna’s train station. Eighty-five people were killed; body parts were everywhere. A neo-fascist group, the Armed Revolutionary Nuclei, claimed credit.
Yet May is correct: modern terrorism is still evolving.
