Pervez Hoodbhoy puts his personal agenda ahead of Pakistani cause here. Saudi influence on Pakistan has been both positive and negative. Iys absolute rubbish that thopse returning from Saudia adopt their culture, rather, those returning are the ones who "educate" the local Pakistani population how poorly they are treated by their saudi "brothers". Pakistan does get a lot of forex from expats in Saudia, it cannot afford to loose it. Sauids have been advanced Pakistans position on international front and has provided free oil. Saudi government has also cracked down on banned organizations collecting funds in KSA like Lashker-toiba and their operatives in Saudia rounded and up. If at all their is any Saudi funding of Madrassa its by some people on their own.
