In the late 1960s, the economic historian Nathaniel Leff began publishing articles explaining why, since the 19th century, Brazil had exhibited slow economic growth and wide discrepancies between rich and poor. His explanations upended what was then, and largely remains, the widely held consensus of Brazilian economists. A devout Orthodox Jew who spent most of his career as a professor at Columbia University, Leff abruptly disappeared from view in the 1990s. Rafael Cariello explains the significance of Leff’s work, recounts his biography, and describes his own personal quest to discover the economist’s fate:

In his scholarly writings, Leff argues that the key to understanding why Brazil became a relatively poor country, with per-capita income far below the levels reached by Europe and the United States, was to be found in the 19th century—no earlier, no later. [By contrast], traditional historiography, which had produced the (still-dominant) narrative about the reasons for the country’s “backwardness,” tended to identify the colonial period [which ended in 1822] and the relationships between Portuguese America and the capitals of Europe as the source of the country’s sluggish pace toward industrialization and development. . . .

For Leff, the causes of Brazil’s underdevelopment also lay in the difficulty that the domestic market faced in articulating itself and growing more quickly, thus creating a complex economy. But instead of pointing the finger at commercial relationships with Europe, he blamed the Brazilian economy’s lack of internal integration—and the high cost of transportation in the country. . . .

As for Leff’s personal story, it tells much about the integration of Jews into American universities. Leff entered Harvard in the 1950s, when Ivy League schools were not entirely comfortable places for Jews. By the time he retired from Columbia, much had changed, as Cariello writes:

[One former colleague recalled Leff] coming to the campus and walking through the gardens and neoclassical buildings at Columbia in a dark hat and coat, with a full white beard. . . . [But in] the small photograph on the diplomatic document authorizing his entry into [Brazil, where he went to conduct research in 1963], Leff shows none of the features commonly associated with religious Jews. Not a hint of a beard, and no kippah. I put this to [his son] Avraham.

“Yes, it makes sense,” he said. “A while ago I was looking at my father’s reunion picture and a picture of him at Harvard. Had I not been told that was my father, I wouldn’t have known. He was totally clean-shaven, no hat, no nothing. This was America in the 1950s, where you didn’t rock the boat if you didn’t have to.” According to his son, Leff let his beard grow out only after he got tenure.

Established in 2012 and maintaining branches in Europe, North America, and Iran, the Samidoun Palestinian Prisoner Network claims its goal is merely to show “solidarity” for imprisoned Palestinians. The organization’s leader, however, has admitted to being a representative of the Popular Front for the Liberation of Palestine (PFLP), a notorious terrorist group whose most recent accomplishments include murdering a seventeen-year-old girl. As Arsen Ostrovsky and Patricia Teitelbaum point out, Samidoun is just one example of how the European Union allows Iran-backed terrorists to operate in its midst:

The PFLP is a proxy of the Iranian regime, which provides the terror group with money, training, and weapons. Samidoun . . . has a branch in Tehran. It has even held events there, under the pretext of “cultural activity,” to elicit support for operations in Europe. Its leader, Khaled Barakat, is a regular on Iran’s state [channel] PressTV, calling for violence and lauding Iran’s involvement in the region. It is utterly incomprehensible, therefore, that the EU has not yet designated Samidoun a terror group.

According to the Council of the European Union, groups and/or individuals can be added to the EU terror list on the basis of “proposals submitted by member states based on a decision by a competent authority of a member state or a third country.” In this regard, there is already a standing designation by Israel of Samidoun as a terror group and a decision of a German court finding Barakat to be a senior PFLP operative.

Given the irrefutable axis-of-terror between Samidoun, PFLP, and the Iranian regime, the EU has a duty to put Samidoun and senior Samidoun leaders on the EU terror list. It should do this not as some favor to Israel, but because otherwise it continues to turn a blind eye to a group that presents a clear and present security threat to the European Union and EU citizens.
