Ishaan Tharoor writes: A lot of ink has already been spilled on the complexity of the jihadist networks operating in Belgium, as well as the social factors — discrimination and alienation — luring some Belgian youths toward groups such as the Islamic State. It’s also worth considering, though, an older history.

Analysts point to the inroads made in Belgium by the more conservative, orthodox brand of Islam espoused by the kingdom of Saudi Arabia. This is the consequence of actual policy. In 1978, the Saudi-backed Great Mosque of Brussels opened its doors; the elegant building and land where it sat had been a gift by Belgium’s then-king to his Saudi counterpart a decade prior.

It became the seat of Islamic activity in Belgium. A 2007 leaked U.S. diplomatic cable, published by the anti-secrecy site WikiLeaks, detailed how the Saudi Embassy in Brussels has continued to provide Korans to myriad mosques in the country and help pay for the upkeep of the structures. Saudi Arabia also invested in training the imams who would preach to a growing Muslim diaspora in European countries, including in Belgium.

Observers say the Salafist dogma of the Saudi-funded clerics active in many mosques in Belgium stood in contrast to the traditional beliefs of the mostly working-class Moroccan and Turkish immigrants who first arrived in the country in the 1960s and 1970s.

“The Moroccan community comes from mountainous regions and rift valleys, not the desert. They come from the Maliki school of Islam, and are a lot more tolerant and open than the Muslims from other regions like Saudi Arabia,” George Dallemagne, a Belgian politician, told the Independent last year. “However, many of them were re-Islamified by the Salafist clerics and teachers from the Great Mosque. Some Moroccans were even given scholarships to study in Medina, in Saudi Arabia.”

The majority of the Belgian nationals who have gone to fight in Syria and Iraq are thought to be of Moroccan descent.

A separate WikiLeaks disclosure — this time of classified Saudi documents — found that in April 2012 the Belgian government quietly forced Saudi authorities to remove the main director of the Great Mosque, Khalid Alabri, a Saudi Embassy employee suspected of propagating the intolerant Sunni radicalism that is shared by the extremists of the Islamic State.
