This is what Wikileaks has released so far:
"While the majority of Brazil’s Muslims are moderate in orientation and the overwhelming majority is moderate in deed and action, genuine radical elements do exist here, some in the Tri-Border area of Foz de Iguacu and others among Sao Paulo’s estimated 20,000-strong, Hezbollah-oriented Shia population. Muslims at the moderate, Sunni-oriented Future Institute charge that Shia immigrants sometimes come to Brazil with Hezbollah support (allegedly USD 50,000 is a typical sum) to found businesses to support Hezbollah in Lebanon." [Nov 2009]
and:
"Sao Paulo's Muslim moderates worry about the rise of fundamentalism and Hezbollah influence among more recent waves of largely Shia Lebanese immigrants, as they promote a broadly tolerant vision of "modern Islam". Their own community remains quite traditional, with women's and youth organizations limited. Even so, the traditional leadership's eagerness to engage, acute awareness of the dangers of radicalism, and their solid achievements in integrating Muslim and Brazilian identities make them an excellent example of how a unique MMC (Muslim Minority Community) has, by and large, carved out a positive space within a diverse Latin American country. ...
As [XXXX], a Lebanese Brazilian banker and Maronite Christian, told SMRC Pandith, "Hezbollah is gaining [adherents]," particularly with more recent Shia Lebanese immigrants. Consequently, the moderates want to "push back against the radicals" by promoting popular interfaith activities. " [December 2009]
