NEW YORK — Walter Laqueur, who fled Nazi Germany as a teenager and, without a college degree, became a distinguished scholar of the Holocaust, the collapse of the Soviet Union, European decline, the Middle East conflict, and global terrorism, died on Sunday at his home in Washington. He was 97.
Mr. Laqueur was a prodigious author who spoke a half-dozen languages and wrote scores of novels, memoirs, and books on geopolitics, in which he could be prescient.
While much of the world was basking in the breakdown of Soviet communism, Mr. Laqueur, whose London apartment overlooked Karl Marx’s grave, was predicting the emergence of “an authoritarian system based on some nationalist populism.”
That is largely what developed, as he wrote in 2015, in “Putinism: Russia and its Future with the West.”
In a new introduction to his 1977 book “A History of Terrorism,” Mr. Laqueur warned that the world was at the dawn of a new era in which “technological progress would put unprecedented destructive power into the hands of a small group” of fanatics bent on inflicting terror in a holy war. That warning was dated June 2001, less than three months before the Sept. 11 terrorist attacks.
In his last book, “The Future of Terrorism: ISIS, Al-Qaeda, and the Alt-Right,” written with Christopher Wall and published this year, Mr. Laqueur cautioned that the Islamic State’s short-lived successes in creating a caliphate demonstrated that “true believers now have a model that they can hope to achieve and acquire, because it has been done.”
Terrorists cannot destroy Western society without weapons of mass destruction, the authors write, but Western nations make themselves more vulnerable if they overreact and bolster domestic security by curtailing civil rights and civil liberties — responses that “perversely accomplish the goals” of the terrorists.
The book ends with a warning to President Trump: Undermining European unity and directing incendiary language at Muslims while singling them out for immigration restrictions make the United States more of a target. “Unless there is some moderation in his policies,” Mr. Laqueur and Wall conclude about the president, “all proposals just seem to increase the probability that people will radicalize and attack.”
Mr. Laqueur was difficult to pigeonhole. He supported Israel but criticized what he viewed as its excesses in expanding settlements in the West Bank.
In the late 1960s he was critical of the counterculture, so much so that Vice President Spiro T. Agnew, a combative conservative voice in the Nixon administration, quoted Mr. Laqueur approvingly when he wrote in Commentary magazine that “the cultural and political idiocies perpetuated with impunity in this permissive age have gone clearly beyond the borders of what is acceptable for any society, however liberally it may be structured.”
What Agnew neglected to quote, however, was Mr. Laqueur’s next sentence: “No one knows whether the right-wing backlash, so long predicted, will in fact make its dreadful appearance.”
Walter Louis Laqueur was born into a Jewish family in Breslau, Germany (now Wroclaw, Poland). His father, Fritz, manufactured overalls. His mother, Elsa (Berliner), was a homemaker. Both were murdered in the Holocaust.
In 1938, when he was 17, Walter fled a few days before Kristallnacht, the November pogrom against Jews by uniformed Nazis and their sympathizers. He found his way to Palestine, where he was known as Ze’ev.
In his writings, he would reduce decades of Middle East discord to a conflict between basic impulses: that of Arabs for pride and dignity and that of Jews for survival, with the Jewish struggle requiring Israel’s neighbors to accept its statehood.
When he visited home after World War II, Mr. Laqueur wrote in his memoir “Thursday’s Child Has Far to Go” (1992), “the world I had known as a boy no longer existed, and as I tried to remember the people I had known when I was 16, I realized that most of them had died a violent death.”
“Some were killed in the ruins of Stalingrad,” he said, “others in Auschwitz, some in 1948 in the battles for Palestine.”
In 1955 he moved to London, where he was a founder and editor of The Journal of Contemporary History.
From 1965 to 1994, he was director of the Wiener Library for the Study of the Holocaust and Genocide, a leading archive in London. He was later editor of The Washington Quarterly, a journal on international affairs.
His marriage to Naomi Koch lasted until her death in 1995. Mr. Laqueur leaves his wife, Susi, two daughters from his first marriage, Sylvia Laqueur Graham and Shlomit; four grandchildren; and 10 great-grandchildren.
Mr. Laqueur was a professor at Georgetown and Brandeis Universities and a visiting professor at several colleges, including Harvard.
His other books include “A History of Zionism” (1972); his memoirs “Worlds Ago” (1992) and “Best of Times, Worst of Times” (2009); “The Terrible Secret” (1980), in which he wrote that early reports of the Nazi “final solution” were not believed by Allied governments nor by Jews themselves; and, as editor, “The Holocaust Encyclopedia” (2001), a definitive compendium.
Professor Bruce Hoffman, a friend and colleague at Georgetown, recalled in a tribute that has not yet been published that Mr. Laqueur “once observed that only pessimists survived the Holocaust.”
“Optimists believed that Hitler could either be controlled or that common sense and decency would somehow eventually prevail,” Hoffman wrote.
Among Laqueur’s last book was “Reflections of a Veteran Pessimist” (2017). The title notwithstanding, he told Der Spiegel that he would have preferred to live during the belle époque, at the end of the 19th century, when hope sprang eternal. He then paused.
“Hope springs eternal,” he repeated. “It’s one of the most frequently quoted verses of English poetry. The poet was Alexander Pope, a decidedly cautious man. He had many enemies, and we know from his sister that he never went out into the street without his large, aggressive dog, and always with two loaded pistols in his bag.”
